# Crypto completion — streaming AEAD, recovery, device keys, scrypt, blake2b, password helpers, hash-password CLI
|
||||
|
||||
**Packages**: `@suaveplan/crypto`, `@suaveplan/crypto-cipher`, `@suaveplan/crypto-curve`, `@suaveplan/crypto-hash`, `@suaveplan/crypto-keys`
|
||||
**Status**: PROPOSED
|
||||
**Type**: feature + spec-conformance
|
||||
|
||||
## Why
|
||||
|
||||
The 2026-05-02 audit of the genesis crypto stack against `../suaveplan/packages/universal/crypto/src` identified seven confirmed feature gaps that the upstream package shipped but the genesis sub-packages do not. None of these are MAJOR architecture changes — they are concrete capabilities (streaming AEAD, ECDSA recovery, device keys, scrypt KDF, blake2b hashing + password helpers, password-driven AEAD wrappers, and the `hash-password` CLI) that downstream consumers (drive, network, audit-logging, slsa) currently work around or block on. Genesis policy (CLAUDE.md §Workflow rule 5) says "preserve the full public surface during rewrites — trimming is OK ONLY when code is duplicated elsewhere in-repo or can be replaced by an existing `@suaveplan/*` library", and none of these seven features are duplicated by anything that already landed.
|
||||
|
||||
Closing all seven in one coordinated pass is preferable to seven small changes because (a) they share validation utilities and `crypto-utils` helpers that have to land at the same revision to avoid mid-port circular pins, (b) the streaming AEAD façade in `crypto/aead` and the engine in `crypto-cipher/primitives` are linked — adding either alone leaves the public surface incoherent, and (c) the password helpers (`encryptWithPassword`, `deriveKeyFromPassword`) sit on top of the new scrypt + blake2b primitives, so they cannot ship until those primitives exist.
|
||||
|
||||
The seven gaps:
|
||||
|
||||
1. **Streaming AEAD** (`crypto-cipher` + `crypto/aead`): `encryptStreamAead` / `decryptStreamAead` async generators (255 L), `aesGcmStreamingEngine` and `xchacha20StreamingEngine` engines (35 L each), `createEncryptionStream` / `createDecryptionStream` Web-Streams adapters, `streamEncrypt` / `streamDecrypt` legacy aliases, `collectStream`, `createStreamKey`, `createStreamEncryption` (430 L of `streaming.ts`).
|
||||
2. **secp256k1 ECDSA recovery** (`crypto-curve/primitives/secp256k1`): `signWithRecovery`, `recoverPublicKey`, `verifyWithRecovery` — all three present in upstream (lines 74, 143, 243 of `signing.ts`) and absent from the genesis 5-method secp256k1 noble engine.
|
||||
3. **Device-key suite** (`crypto-keys/keypair/device`): `createDeviceKey`, `deriveDeviceKeyFromMaster`, `generateDeviceUUID`, `extractDeviceMetadata`, `compareDeviceKeys`, `isValidDeviceKey`, plus `generateDerivedDeviceId` for one-release back-compat (261 L of `device.ts`).
|
||||
4. **scrypt KDF** (`crypto-hash/primitives/scrypt`): N/r/p parameter set, salt + outputLength, async via `@noble/hashes/scrypt` (53 L of `hashing.ts` lines L273-L325).
|
||||
5. **blake2b hashing** (`crypto-hash/primitives/blake2b`): variable output length, optional key, plus `hashPasswordBlake2b` / `verifyPasswordBlake2b` constant-time wrappers with the parameterised `$blake2b$v=1$cf=N$salt$hash` format.
|
||||
6. **encryptWithPassword + deriveKeyFromPassword** (`crypto/password`): the high-level "password → encrypted blob" pattern (Argon2id-derived key + AEAD), 344 L of `password.ts`.
|
||||
7. **`hash-password` CLI bin** (new `packages/crypto/crypto-bin` or `crypto/bin/hash-password.ts`): a one-shot CLI that hashes a plaintext password to a verifier and exits 0/1 on verify (98 L of `bin/hash-password.ts`).
|
||||
|
||||
## What changes
|
||||
|
||||
### `@suaveplan/crypto-cipher`
|
||||
|
||||
- ADDED: `streaming/streaming-aead.ts` — `encryptStreamAead` and `decryptStreamAead` async generators with chunk-level header / footer tags, `EncryptStreamAeadOptions` and `DecryptStreamAeadOptions` (chunk size, AAD, AbortSignal, optional `header` callback for chunk-tag attestation).
|
||||
- ADDED: `streaming/streaming-aead-aes-gcm.ts` — `aesGcmStreamingEngine: StreamingAeadEngine` adapter built on the existing `aes-256-gcm` primitive; nonce per chunk derived from a 12-byte base nonce + 32-bit counter (RFC 5116-compatible).
|
||||
- ADDED: `streaming/streaming-aead-xchacha20.ts` — `xchacha20StreamingEngine: StreamingAeadEngine` adapter built on the existing `xchacha20-poly1305` primitive; nonce per chunk derived from a 24-byte base nonce + 32-bit counter.
|
||||
- ADDED: `streaming/streaming-aead.types.ts` — `StreamingAeadEngine` interface, `StreamingChunkTag` interface, `StreamingHeader` interface.
|
||||
- ADDED: error codes `CRYPTO_CIPHER.STREAM_TAG_MISMATCH`, `CRYPTO_CIPHER.STREAM_OUT_OF_ORDER`, `CRYPTO_CIPHER.STREAM_ABORTED`, `CRYPTO_CIPHER.STREAM_INVALID_NONCE_BASE`.
|
||||
|
||||
### `@suaveplan/crypto-curve`
|
||||
|
||||
- ADDED: `primitives/secp256k1/impl/secp256k1.noble/secp256k1.noble.ts` exports `signWithRecovery(digest, privateKey)`, `recoverPublicKey(signatureWithRecovery, digest)`, and `verifyWithRecovery(signatureWithRecovery, digest, expectedPublicKey)`. The signature-with-recovery byte layout is the canonical 65-byte form (64-byte compact signature + 1 recovery byte).
|
||||
- ADDED: `primitives/secp256k1/impl/secp256k1.native/secp256k1.native.ts` matching surface (libsodium does not ship secp256k1 — native engine throws `CRYPTO_CURVE.PRIMITIVE_NOT_IMPLEMENTED` per genesis convention).
|
||||
- MODIFIED: `secp256k1.select` re-exports the three new functions.
|
||||
- ADDED: error codes `CRYPTO_CURVE.RECOVERY_BYTE_MISSING`, `CRYPTO_CURVE.RECOVERY_BYTE_INVALID`, `CRYPTO_CURVE.RECOVERED_KEY_MISMATCH`.
|
||||
|
||||
### `@suaveplan/crypto-hash`
|
||||
|
||||
- ADDED: `primitives/scrypt/scrypt.ts` — `scrypt(password, salt, options)` with `N`, `r`, `p`, `dkLen` parameters; uses `@noble/hashes/scrypt`'s `scryptAsync`.
|
||||
- ADDED: `primitives/scrypt/scrypt.select` and `primitives/scrypt/impl/scrypt.noble/scrypt.noble.ts` matching the existing per-primitive selector layout.
|
||||
- ADDED: `primitives/blake2b/blake2b.ts` — `blake2b(message, options)` with `dkLen` (1–64 bytes), optional `key`, optional `salt`, optional `personalization`.
|
||||
- ADDED: `primitives/blake2b/blake2b.select` and `primitives/blake2b/impl/blake2b.noble/blake2b.noble.ts`.
|
||||
- ADDED: `mac/blake2b-password/blake2b-password.ts` — `hashPasswordBlake2b(password, options)` and `verifyPasswordBlake2b(storedHash, password)`, using the `$blake2b$v=1$cf=<costFactor>$<saltHex>$<hashHex>` MCF-style format and constant-time comparison.
|
||||
- ADDED: error codes `CRYPTO_HASH.SCRYPT_INVALID_N`, `CRYPTO_HASH.BLAKE2B_OUTPUT_TOO_LONG`, `CRYPTO_HASH.BLAKE2B_KEY_TOO_LONG`, `CRYPTO_HASH.BLAKE2B_PASSWORD_FORMAT_INVALID`.
|
||||
|
||||
### `@suaveplan/crypto-keys`
|
||||
|
||||
- ADDED: `keypair/device/device.ts` — `createDeviceKey`, `deriveDeviceKeyFromMaster`, `generateDeviceUUID`, `extractDeviceMetadata`, `compareDeviceKeys`, `isValidDeviceKey`, plus the `generateDerivedDeviceId` back-compat alias.
|
||||
- ADDED: `keypair/device/device.types.ts` — `DeviceKey`, `MasterKey`, `DeviceKeyOptions`, `DeviceKeyDerivationOptions`, `DeviceIdOptions`, `DeviceMetadata` interfaces.
|
||||
- ADDED: error codes `CRYPTO_KEYS.DEVICE_INVALID_MASTER`, `CRYPTO_KEYS.DEVICE_INVALID_KEY`, `CRYPTO_KEYS.DEVICE_DERIVATION_FAILED`.
|
||||
|
||||
### `@suaveplan/crypto`
|
||||
|
||||
- ADDED: `aead/streaming/streaming-aead.ts` — high-level façade `encryptStreamAead` / `decryptStreamAead` that selects the engine (`xchacha20-poly1305` or `aes-256-gcm`) from the opts argument and delegates to `crypto-cipher`. Re-exports `aesGcmStreamingEngine` and `xchacha20StreamingEngine`.
|
||||
- ADDED: `aead/streaming/web-streams.ts` — `createEncryptionStream(opts)` and `createDecryptionStream(opts)` returning `TransformStream<Uint8Array, Uint8Array>` Web-Streams adapters; `collectStream(stream)`, `createStreamKey(rng?)`, `createStreamEncryption(opts)` helpers; `streamEncrypt` / `streamDecrypt` aliases preserved for back-compat.
|
||||
- ADDED: `password/encrypt-with-password.ts` — `encryptWithPassword(password, plaintext, options?)` and `decryptWithPassword(password, ciphertext, options?)`. Default KDF is Argon2id; opt into scrypt via `kdf: "scrypt"` in options. Default cipher is `xchacha20-poly1305`. Output is a self-describing binary header (`magic`, `kdf`, `kdfParams`, `cipher`, `salt`, `nonce`) followed by the ciphertext.
|
||||
- ADDED: `password/derive-key-from-password.ts` — `deriveKeyFromPassword(password, salt, options?)` returning a 32-byte `Uint8Array` suitable for use as a symmetric key. KDF selection (`argon2id` / `scrypt` / `pbkdf2`) is via the options bundle.
|
||||
- ADDED: error codes `CRYPTO.STREAM_AEAD_HEADER_INVALID`, `CRYPTO.PASSWORD_KDF_UNKNOWN`, `CRYPTO.PASSWORD_BLOB_HEADER_INVALID`, `CRYPTO.PASSWORD_BLOB_VERSION_UNSUPPORTED`.
|
||||
|
||||
### `@suaveplan/crypto-bin` (new package)
|
||||
|
||||
- ADDED: a thin CLI package `packages/crypto/crypto-bin` whose only purpose is to ship the `hash-password` bin. Per-Suaveplan policy CLI surfaces live in their own package so they do not leak `@suaveplan/cli` runtime deps into the universal-tier `@suaveplan/crypto`. Depends on `@suaveplan/cli`, `@suaveplan/crypto-hash`, `@suaveplan/error`. Bin: `suaveplan-hash-password`. Reads a password from stdin or `--password`, writes a verifier hash (Argon2id by default, `--algo blake2b` opt-in) to stdout; with `--verify <stored>` reads `--password` and exits `0` on match, `1` on mismatch.
|
||||
|
||||
## Out of scope
|
||||
|
||||
- **Post-quantum signature primitives** (Dilithium, SPHINCS+, ML-KEM key-encapsulation) — separate `crypto-pqc-*` family of sub-packages already discussed in `STATUS.md`. Adding PQC primitives requires a separate engine adapter substrate that is larger than this entire change.
|
||||
- **FIDO2 / WebAuthn helpers** — already covered by browser-tier deps in the genesis app shells; no upstream parity gap here.
|
||||
- **HSM / KMS adapters** (CloudHSM, AWS KMS, GCP KMS) — operational concern, not a library gap; tracked separately under the audit-logging adapter family.
|
||||
- **Argon2id parameter migration helper** — upstream ships `migrateArgon2idParams(oldHash, newOptions)` for re-hashing on login. Genesis already routes Argon2id verification through `crypto-hash/primitives/argon2id` and migration belongs in a future `auth` change, not in `crypto-hash`.
|
||||
- **Modifying the existing Argon2id primitive** — the new `encryptWithPassword` defers to the existing `argon2id` primitive without changing its signature.
|
||||
- **`crypto-vault` integration** — `crypto-vault` already wraps Argon2id-hardened HD derivation; once `scrypt` lands in `crypto-hash`, a follow-up change can add a `kdf: "scrypt"` option to the vault. Out of scope here to keep this change focused on the seven enumerated gaps.
|
||||
|
||||
## Source mapping
|
||||
|
||||
Genesis `enterprise/crypto.md` is a generic enterprise-quality template (no per-feature requirements), so source mapping cites the upstream package source directly.

|
||||
|
||||
### Requirements with no source line
|
||||
|
||||
| Requirement | Justification |
|
||||
|---|---|
|
||||
| `StreamingAeadEngine` interface (formal) | Upstream uses a duck-typed object; genesis convention is a named interface in a `*.types.ts` file (see CLAUDE.md §11 "No nested object literals in interfaces"). |
|
||||
| Error codes mapped to `@suaveplan/error` (`CRYPTO_CIPHER.STREAM_*`, `CRYPTO_CURVE.RECOVERY_*`, `CRYPTO_KEYS.DEVICE_*`, `CRYPTO_HASH.SCRYPT_*` / `BLAKE2B_*`, `CRYPTO.PASSWORD_*`) | Genesis-wide policy: every thrown error routes through `@suaveplan/error` with a stable code. Upstream throws plain `Error` / `PasswordError`. |
|
||||
| `crypto-bin` as its own package | Universal-tier `@suaveplan/crypto` cannot depend on `@suaveplan/cli` (CLI is browser/server-tier and pulls in `@suaveplan/readline`). Splitting the CLI out keeps `crypto` zero-side-effect and tree-shakeable. |
|
||||
| `encryptWithPassword` self-describing binary header | Upstream stores `salt + ciphertext` only; consumers had to know the iteration count externally. Genesis adds a versioned 16-byte header (`magic[4] \| version[1] \| kdf[1] \| cipher[1] \| reserved[1] \| saltLen[2] \| nonceLen[2] \| kdfParamsLen[4]`) so a blob is self-descriptive and rotation-safe. |
|
||||
| `decryptWithPassword` companion to `encryptWithPassword` | Upstream's `decryptWithPassword` (L115-L160 of `password.ts`) is included. Listed here only because the proposal text earlier groups gap 6 as one verb; this row exists so reviewers can see both halves are covered. |
|
||||
| `signWithRecovery` / `recoverPublicKey` / `verifyWithRecovery` exposed at `secp256k1.noble.ts` rather than the higher-level `signing.ts` | Upstream's `signing.ts` is a multi-key façade that pulls `BaseKeySchema` plumbing genesis hasn't ported. Putting the three functions on the curve primitive (where they belong cryptographically) avoids a circular dep with `crypto-keys`. |
|
||||
|
||||
## Verification approach
|
||||
|
||||
Each spec delta requirement carries a `**Verified by:**` line pointing at concrete `it(...)` titles. The test files that will exist after this change ships:
|
||||
|
||||
- `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.test.ts` — chunk round-trip per engine; tag mismatch detection; abort propagation
|
||||
- `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.spec-conformance.test.ts` — `StreamingAeadEngine` contract pinned for both adapters; nonce-counter monotonicity; out-of-order chunks emit `STREAM_OUT_OF_ORDER`
|
||||
- `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.test.ts` — extended with sign/recover/verify-with-recovery cases; recovery byte 0/1 round-trip
|
||||
- `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.spec-conformance.test.ts` — invalid recovery byte emits `RECOVERY_BYTE_INVALID`; missing recovery byte emits `RECOVERY_BYTE_MISSING`; recovered key mismatch emits `RECOVERED_KEY_MISMATCH`
|
||||
- `packages/crypto/crypto-hash/src/primitives/scrypt/scrypt.test.ts` — KAT round-trip vs upstream RFC 7914 vectors; `dkLen` 32 / 64 / 128
|
||||
- `packages/crypto/crypto-hash/src/primitives/scrypt/scrypt.spec-conformance.test.ts` — invalid `N` (non-power-of-two, < 2) emits `SCRYPT_INVALID_N`
|
||||
- `packages/crypto/crypto-hash/src/primitives/blake2b/blake2b.test.ts` — RFC 7693 KAT round-trip; output length 1..64; keyed mode
|
||||
- `packages/crypto/crypto-hash/src/primitives/blake2b/blake2b.spec-conformance.test.ts` — output > 64 emits `BLAKE2B_OUTPUT_TOO_LONG`; key > 64 emits `BLAKE2B_KEY_TOO_LONG`
|
||||
- `packages/crypto/crypto-hash/src/mac/blake2b-password/blake2b-password.test.ts` — round-trip hash → verify; salt freshness across calls; constant-time comparison observable via timing-side-channel test
|
||||
- `packages/crypto/crypto-hash/src/mac/blake2b-password/blake2b-password.spec-conformance.test.ts` — malformed stored hash emits `BLAKE2B_PASSWORD_FORMAT_INVALID`
|
||||
- `packages/crypto/crypto-keys/src/keypair/device/device.test.ts` — `createDeviceKey` round-trip; `deriveDeviceKeyFromMaster` deterministic; `generateDeviceUUID` valid v4; `extractDeviceMetadata` round-trip; `compareDeviceKeys` constant-time
|
||||
- `packages/crypto/crypto-keys/src/keypair/device/device.spec-conformance.test.ts` — invalid master emits `DEVICE_INVALID_MASTER`; corrupt key emits `DEVICE_INVALID_KEY`
|
||||
- `packages/crypto/crypto/src/aead/streaming/streaming-aead.test.ts` — façade selects correct engine; round-trip per `xchacha20-poly1305` and `aes-256-gcm`
|
||||
- `packages/crypto/crypto/src/aead/streaming/web-streams.test.ts` — Web-Streams round-trip; `collectStream` aggregates correctly; `streamEncrypt` / `streamDecrypt` aliases match the canonical functions
|
||||
- `packages/crypto/crypto/src/password/encrypt-with-password.test.ts` — round-trip `encrypt → decrypt`; KDF selection (`argon2id` vs `scrypt`); blob header self-descriptive (different KDF params produce different headers; reading a v1 blob with a v2 reader emits `PASSWORD_BLOB_VERSION_UNSUPPORTED`)
|
||||
- `packages/crypto/crypto/src/password/encrypt-with-password.spec-conformance.test.ts` — `kdf: "unknown"` emits `PASSWORD_KDF_UNKNOWN`; truncated blob emits `PASSWORD_BLOB_HEADER_INVALID`
|
||||
- `packages/crypto/crypto/src/password/derive-key-from-password.test.ts` — KDF selection; deterministic given fixed salt + params; output length is exactly 32 bytes
|
||||
- `packages/crypto/crypto-bin/src/hash-password/hash-password.test.ts` — Argon2id mode end-to-end (hash, then verify, exit 0); blake2b mode end-to-end; bad password verify exits 1; missing `--password` arg emits non-zero exit
|
||||
- `packages/crypto/crypto-bin/src/hash-password/hash-password.spec-conformance.test.ts` — error path emits `CRYPTO.HASH_PASSWORD_CLI_*` codes (one per known failure mode)
|
||||
|
||||
## Migration impact
|
||||
|
||||
This change is **additive** — it does not modify any existing public surface. Verification:
|
||||
|
||||
- Existing `@suaveplan/crypto` consumers (`crypto-vault`, `slsa`, `audit-logging`, `auth`, `streams`, `bitpacker-crypto`, `drive-plugin-chunks`, `data/packer`) — none use `signWithRecovery` / streaming AEAD / device keys / scrypt / blake2b / `encryptWithPassword` / hash-password CLI today (the symbols don't exist on genesis). New exports therefore have zero callers at land time.
|
||||
- Existing `crypto-cipher` callers (`crypto`, `crypto-sodium`) — only consume the three primitive selectors (`aes-256-gcm`, `chacha20-poly1305`, `xchacha20-poly1305`). The new `streaming/*` subpath is an isolated subtree.
|
||||
- Existing `crypto-curve` callers (`crypto`) — only consume the four primitive selectors. The three new `signWithRecovery` / `recoverPublicKey` / `verifyWithRecovery` exports do not collide with the existing `sign` / `verify`.
|
||||
- Existing `crypto-hash` callers (`crypto`, `crypto-vault`, `crypto-curve`) — consume `sha256`, `sha384`, `sha512`, `hmac`, `hkdf`, `pbkdf2`, `argon2id`. The new `scrypt` and `blake2b` primitives are isolated.
|
||||
- Existing `crypto-keys` callers (`crypto-vault`, `auth`) — consume `Keychain` and `keypair/{generate,validate}`. The new `keypair/device` subtree is isolated.
|
||||
|
||||
A `bunx turbo build typecheck test --filter=...@suaveplan/crypto*` sweep runs in §9 of `tasks.md` to verify all dependents compile and test green before archive.
|
||||
|
||||
## Impact
|
||||
|
||||
### Affected dependents
|
||||
|
||||
Run `bunx turbo ls --filter=...@suaveplan/crypto` to enumerate. For each dependent, check one box:
|
||||
|
||||
- `@suaveplan/crypto-sodium` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes only the existing AEAD / sign / agree façade; new streaming / password helpers are additive subpaths)
|
||||
- `@suaveplan/crypto-browser` — [ ] tests run / [ ] docs reviewed / [x] no action needed (same — consumes existing AEAD / sign / agree façade)
|
||||
- `@suaveplan/crypto-vault` — [x] tests run / [x] docs reviewed / [ ] no action needed (vault may want to opt into `scrypt` KDF in a follow-up; verifying it still typechecks is required because it imports `crypto-hash` directly)
|
||||
- `@suaveplan/crypto-keys` — [x] tests run / [x] docs reviewed / [ ] no action needed (we are *adding* `keypair/device/*` to it in this change, so its own tests must run)
|
||||
- `@suaveplan/auth` — [x] tests run / [ ] docs reviewed / [ ] no action needed (consumes `crypto-keys`, depends on us not breaking the existing `keypair/{generate,validate}` exports)
|
||||
- `@suaveplan/audit-logging` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes only the AEAD façade for log encryption — new streaming subpath does not collide)
|
||||
- `@suaveplan/slsa` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes only `crypto/sign` for in-toto attestation signing — `signWithRecovery` is a new export, not a modification)
|
||||
- `@suaveplan/streams` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes only the existing primitive selectors)
|
||||
- `@suaveplan/bitpacker-crypto` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes the AEAD façade for packed-bit encryption — new exports do not collide)
|
||||
- `@suaveplan/drive-plugin-chunks` — [ ] tests run / [ ] docs reviewed / [x] no action needed (consumes the AEAD façade for at-rest chunk encryption — new streaming subpath is a candidate for a follow-up port, not a regression risk here)

# Capability Spec Delta: crypto-bin (crypto-completion)
|
||||
|
||||
**Package**: `@suaveplan/crypto-bin`
|
||||
**Status**: PROPOSED
|
||||
|
||||
> Every requirement below carries a `**Verified by:**` line at authoring time. This is a new package; the entire spec below is `## ADDED Requirements`.
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: hash-password CLI hash mode
|
||||
|
||||
The package SHALL ship a `suaveplan-hash-password` bin that, when invoked with `--password <pw>` and no `--verify`, hashes the password using the requested algorithm (default `argon2id`, opt-in `--algo blake2b`) and writes the resulting stored-hash string to stdout, exiting with code 0. The CLI SHALL route through `@suaveplan/cli`'s arg parser (so `--help` works automatically) and SHALL NEVER call `process.exit` directly — it SHALL use `cli.exit(code)` to keep test harness compatibility.
|
||||
|
||||
#### Scenario: argon2id mode prints stored hash
|
||||
|
||||
- **WHEN** `suaveplan-hash-password --password "correct horse battery staple"` is invoked
|
||||
- **THEN** stdout contains a string starting with `"$argon2id$"` AND the exit code is 0
|
||||
|
||||
#### Scenario: blake2b mode prints stored hash
|
||||
|
||||
- **WHEN** `suaveplan-hash-password --password "..." --algo blake2b` is invoked
|
||||
- **THEN** stdout contains a string starting with `"$blake2b$"` AND the exit code is 0
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-bin/src/hash-password/hash-password.test.ts::"argon2id mode writes a $argon2id$-prefixed hash to stdout and exits 0"` AND `packages/crypto/crypto-bin/src/hash-password/hash-password.test.ts::"blake2b mode writes a $blake2b$-prefixed hash to stdout and exits 0"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: hash-password CLI verify mode
|
||||
|
||||
When invoked with `--password <pw>` and `--verify <stored>`, the bin SHALL detect the algorithm from the stored hash's prefix, run the matching verify function (`verifyPasswordArgon2id` or `verifyPasswordBlake2b`), exit with code 0 on match and code 1 on mismatch. The bin SHALL NOT print anything to stdout in verify mode (so the exit code is the only signal — suitable for use in shell pipelines).
|
||||
|
||||
#### Scenario: matching password exits 0
|
||||
|
||||
- **WHEN** the stored hash and the password agree
|
||||
- **THEN** the exit code is 0 AND stdout is empty
|
||||
|
||||
#### Scenario: non-matching password exits 1
|
||||
|
||||
- **WHEN** the stored hash and the password disagree
|
||||
- **THEN** the exit code is 1 AND stdout is empty
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-bin/src/hash-password/hash-password.test.ts::"verify mode exits 0 when password matches stored hash"` AND `packages/crypto/crypto-bin/src/hash-password/hash-password.test.ts::"verify mode exits 1 when password does not match stored hash"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: hash-password CLI argument validation
|
||||
|
||||
The bin SHALL reject malformed invocations (missing `--password`, unknown `--algo`, malformed `--verify` value) with a non-zero exit code and a `SuaveplanError` whose code is one of `CRYPTO.HASH_PASSWORD_CLI_BAD_ARGS`, `CRYPTO.HASH_PASSWORD_CLI_UNKNOWN_ALGO`, or `CRYPTO.HASH_PASSWORD_CLI_VERIFY_FAILED`. The error message SHALL be human-readable and SHALL be printed to stderr (not stdout, so it does not contaminate pipe output).
|
||||
|
||||
#### Scenario: missing --password rejected
|
||||
|
||||
- **WHEN** `suaveplan-hash-password` is invoked with no `--password`
|
||||
- **THEN** the exit code is non-zero AND stderr mentions `--password` AND the underlying error code is `CRYPTO.HASH_PASSWORD_CLI_BAD_ARGS`
|
||||
|
||||
#### Scenario: unknown algorithm rejected
|
||||
|
||||
- **WHEN** `suaveplan-hash-password --password pw --algo bcrypt` is invoked
|
||||
- **THEN** the exit code is non-zero AND the underlying error code is `CRYPTO.HASH_PASSWORD_CLI_UNKNOWN_ALGO` AND `context.algo === "bcrypt"`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-bin/src/hash-password/hash-password.spec-conformance.test.ts::"missing --password emits HASH_PASSWORD_CLI_BAD_ARGS"` AND `packages/crypto/crypto-bin/src/hash-password/hash-password.spec-conformance.test.ts::"unknown --algo emits HASH_PASSWORD_CLI_UNKNOWN_ALGO"`

# Capability Spec Delta: crypto-cipher (crypto-completion)
|
||||
|
||||
**Package**: `@suaveplan/crypto-cipher`
|
||||
**Status**: PROPOSED
|
||||
|
||||
> Every requirement below carries a `**Verified by:**` line at authoring time.
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: Streaming AEAD encryption / decryption
|
||||
|
||||
The package SHALL expose `encryptStreamAead(source, options)` and `decryptStreamAead(source, options)` async generators that consume a `Uint8Array` input stream chunk by chunk, attach a per-chunk authentication tag, and emit the encrypted (or decrypted) chunk stream. Each chunk SHALL use a per-chunk nonce derived deterministically from a base nonce plus a 32-bit chunk counter so the entire stream binds to a single key without nonce reuse.
|
||||
|
||||
#### Scenario: round-trip preserves bytes
|
||||
|
||||
- **WHEN** `encryptStreamAead(plaintext, { algorithm, key, baseNonce })` is consumed and its output is fed to `decryptStreamAead(ciphertext, { algorithm, key, baseNonce })`
|
||||
- **THEN** the concatenated output equals the original plaintext byte-for-byte
|
||||
|
||||
#### Scenario: tag mismatch detected on tampered chunk
|
||||
|
||||
- **WHEN** any byte of any encrypted chunk's tag is flipped before decryption
|
||||
- **THEN** `decryptStreamAead` throws a `SuaveplanError` with code `CRYPTO_CIPHER.STREAM_TAG_MISMATCH` and `context.chunkIndex` points at the tampered chunk
|
||||
|
||||
#### Scenario: chunk-counter overflow rejected
|
||||
|
||||
- **WHEN** the chunk counter reaches `2^32`
|
||||
- **THEN** the next chunk emission throws `CRYPTO_CIPHER.STREAM_OUT_OF_ORDER` with `context.counter === 2 ** 32`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.test.ts::"round-trips a multi-chunk plaintext through encryptStreamAead and decryptStreamAead"` AND `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.test.ts::"throws STREAM_TAG_MISMATCH when a chunk tag is flipped"` AND `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.spec-conformance.test.ts::"throws STREAM_OUT_OF_ORDER on chunk-counter overflow"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: AbortSignal propagation through streaming AEAD
|
||||
|
||||
The package SHALL honour an optional `AbortSignal` passed via `EncryptStreamAeadOptions.signal` and `DecryptStreamAeadOptions.signal`. When the signal is aborted mid-stream the generator SHALL flush the in-flight chunk, release any pending cipher state, and throw `SuaveplanError` with code `CRYPTO_CIPHER.STREAM_ABORTED`.
|
||||
|
||||
#### Scenario: abort mid-stream rejects with STREAM_ABORTED
|
||||
|
||||
- **WHEN** an `AbortController` is signalled while `encryptStreamAead` is mid-iteration
|
||||
- **THEN** the next `await generator.next()` rejects with `CRYPTO_CIPHER.STREAM_ABORTED` and `context.chunksProcessed` reflects the count emitted before abort
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.test.ts::"aborts mid-stream and rejects with STREAM_ABORTED"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: AES-GCM streaming engine adapter
|
||||
|
||||
The package SHALL expose `aesGcmStreamingEngine: StreamingAeadEngine` that wraps the existing `aes-256-gcm` primitive. Per-chunk nonce SHALL be a 12-byte big-endian concatenation of an 8-byte caller-supplied prefix and a 4-byte chunk counter (RFC 5116 §3.2 compatible). The engine SHALL reject `baseNonce.length !== 8` with `CRYPTO_CIPHER.STREAM_INVALID_NONCE_BASE`.
|
||||
|
||||
#### Scenario: 8-byte base nonce accepted
|
||||
|
||||
- **WHEN** `aesGcmStreamingEngine.encrypt({ baseNonce: 8-byte prefix, key, plaintext, counter: 0 })` is called
|
||||
- **THEN** the produced nonce equals `baseNonce ‖ counter_be32(0)` (12 bytes total)
|
||||
|
||||
#### Scenario: wrong-length base nonce rejected
|
||||
|
||||
- **WHEN** `baseNonce.length === 12`
|
||||
- **THEN** the engine throws `CRYPTO_CIPHER.STREAM_INVALID_NONCE_BASE` with `context.expectedLength === 8` and `context.actualLength === 12`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-cipher/src/streaming/streaming-aead-aes-gcm/streaming-aead-aes-gcm.test.ts::"derives 12-byte nonce from 8-byte base + counter"` AND `packages/crypto/crypto-cipher/src/streaming/streaming-aead-aes-gcm/streaming-aead-aes-gcm.spec-conformance.test.ts::"rejects wrong-length base nonce with STREAM_INVALID_NONCE_BASE"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: XChaCha20-Poly1305 streaming engine adapter
|
||||
|
||||
The package SHALL expose `xchacha20StreamingEngine: StreamingAeadEngine` that wraps the existing `xchacha20-poly1305` primitive. Per-chunk nonce SHALL be a 24-byte big-endian concatenation of a 20-byte caller-supplied prefix and a 4-byte chunk counter. The engine SHALL reject `baseNonce.length !== 20` with `CRYPTO_CIPHER.STREAM_INVALID_NONCE_BASE`.
|
||||
|
||||
#### Scenario: 20-byte base nonce accepted
|
||||
|
||||
- **WHEN** `xchacha20StreamingEngine.encrypt({ baseNonce: 20-byte prefix, key, plaintext, counter: 5 })` is called
|
||||
- **THEN** the produced nonce equals `baseNonce ‖ counter_be32(5)` (24 bytes total)
|
||||
|
||||
#### Scenario: wrong-length base nonce rejected
|
||||
|
||||
- **WHEN** `baseNonce.length === 24`
|
||||
- **THEN** the engine throws `CRYPTO_CIPHER.STREAM_INVALID_NONCE_BASE` with `context.expectedLength === 20` and `context.actualLength === 24`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-cipher/src/streaming/streaming-aead-xchacha20/streaming-aead-xchacha20.test.ts::"derives 24-byte nonce from 20-byte base + counter"` AND `packages/crypto/crypto-cipher/src/streaming/streaming-aead-xchacha20/streaming-aead-xchacha20.spec-conformance.test.ts::"rejects wrong-length base nonce with STREAM_INVALID_NONCE_BASE"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: StreamingAeadEngine contract
|
||||
|
||||
The package SHALL define a `StreamingAeadEngine` interface in `streaming-aead.types.ts` with `encrypt(input: StreamingChunkInput): Promise<StreamingChunkOutput>` and `decrypt(input: StreamingChunkInput): Promise<Uint8Array>` methods, plus `nonceBaseLength: number` and `tagLength: number` constants. Both built-in engines (AES-GCM, XChaCha20-Poly1305) SHALL satisfy this interface and SHALL be substitutable for any caller-supplied engine.
|
||||
|
||||
#### Scenario: caller-supplied engine round-trips identically
|
||||
|
||||
- **WHEN** a custom `StreamingAeadEngine` implementation is passed to `encryptStreamAead` and the same instance to `decryptStreamAead`
|
||||
- **THEN** the round-trip preserves bytes byte-for-byte (validated against an in-test spy engine that records every call)
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.spec-conformance.test.ts::"StreamingAeadEngine contract is stable for custom engines"`

# Capability Spec Delta: crypto-curve (crypto-completion)
|
||||
|
||||
**Package**: `@suaveplan/crypto-curve`
|
||||
**Status**: PROPOSED
|
||||
|
||||
> Every requirement below carries a `**Verified by:**` line at authoring time.
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: secp256k1 ECDSA signing with recovery byte
|
||||
|
||||
The `secp256k1` primitive SHALL expose `signWithRecovery(digest, privateKey)` returning a 65-byte signature (64-byte compact signature followed by a single recovery byte). The recovery byte SHALL be the byte returned by `secp256k1.sign(digest, privateKey).recovery` from the `@noble/curves` library; valid values are `0` or `1`.
|
||||
|
||||
#### Scenario: produces 65-byte signature
|
||||
|
||||
- **WHEN** `signWithRecovery(digest, privateKey)` is called for a valid digest and private key
|
||||
- **THEN** the result is a `Uint8Array` of length 65 AND `result[64]` is `0` or `1`
|
||||
|
||||
#### Scenario: signWithRecovery output verifies via standard verify
|
||||
|
||||
- **WHEN** the first 64 bytes of `signWithRecovery(digest, privateKey)` are passed to the existing `verify(digest, sig64, publicKey)`
|
||||
- **THEN** the signature verifies successfully
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.test.ts::"signWithRecovery returns 65-byte signature with recovery byte 0 or 1"` AND `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.test.ts::"signWithRecovery output verifies via standard verify on first 64 bytes"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: secp256k1 public-key recovery
|
||||
|
||||
The `secp256k1` primitive SHALL expose `recoverPublicKey(signatureWithRecovery, digest)` returning the 33-byte compressed public key recovered from a 65-byte signature-with-recovery and the original digest. Inputs may be supplied as `Uint8Array` or hex strings.
|
||||
|
||||
#### Scenario: recovers the signing public key
|
||||
|
||||
- **WHEN** `signWithRecovery(digest, privateKey)` produces `sig` and `recoverPublicKey(sig, digest)` is called
|
||||
- **THEN** the recovered public key equals `getPublicKey(privateKey)` byte-for-byte
|
||||
|
||||
#### Scenario: missing recovery byte rejected
|
||||
|
||||
- **WHEN** a 64-byte signature (without recovery byte) is passed to `recoverPublicKey`
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO_CURVE.RECOVERY_BYTE_MISSING` and `context.signatureLength === 64`
|
||||
|
||||
#### Scenario: invalid recovery byte rejected
|
||||
|
||||
- **WHEN** a 65-byte signature is passed but `signatureWithRecovery[64]` is `2`, `3`, or any value > 3
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO_CURVE.RECOVERY_BYTE_INVALID` and `context.recoveryByte` reflects the offending value
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.test.ts::"recoverPublicKey returns the same key as getPublicKey for the signer"` AND `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.spec-conformance.test.ts::"throws RECOVERY_BYTE_MISSING for 64-byte signature"` AND `packages/crypto/crypto-curve/src/primitives/secp256k1/secp256k1.spec-conformance.test.ts::"throws RECOVERY_BYTE_INVALID when recovery byte is out of range"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: secp256k1 verify-with-recovery
|
||||
|
||||
The `secp256k1` primitive SHALL expose `verifyWithRecovery(signatureWithRecovery, digest, expectedPublicKey)` returning `true` only when the public key recovered from the signature equals `expectedPublicKey` (compared in constant time on the byte buffer). When the recovered key differs, the function SHALL return `false` (it does NOT throw on mismatch — mismatch is a routine path).
|
||||
|
||||
#### Scenario: returns true on matching key
|
||||
|
||||
- **WHEN** `verifyWithRecovery(sig, digest, expectedPublicKey)` is called with the public key that produced `sig`
|
||||
- **THEN** the result is `true`
|
||||
|
||||
#### Scenario: returns false on non-matching key
|
||||
|
||||
- **WHEN** `verifyWithRecovery(sig, digest, otherPublicKey)` is called with a public key that did not produce `sig`
|
||||
- **THEN** the result is `false` (no exception is thrown)
|
||||
|
||||
#### Scenario: comparison is constant-time
|
||||
|
||||
- **WHEN** the recovered public key and `expectedPublicKey` differ in their first byte vs differ only in their last byte
|
||||
- **THEN** the timing distribution observed across many invocations does not reveal the position of the difference (verified via a statistical timing test)

The implementation SHALL match RFC 7914 byte-for-byte and SHALL use the `@noble/hashes/scrypt::scryptAsync` engine in the noble selector. Output is a `Uint8Array` of length `dkLen`.
|
||||
|
||||
#### Scenario: matches RFC 7914 known-answer test

|
||||
|
||||
- **WHEN** `blake2b("abc", { dkLen: 64 })` is called

|
||||
|
||||
### Requirement: blake2b password hashing and verification
|
||||
|
||||
The package SHALL expose `hashPasswordBlake2b(password, options)` returning a stored hash in the format `$blake2b$v=1$cf=<costFactor>$<saltHex>$<hashHex>`, where `costFactor` controls iteration count (default 14, doubling each level) and a 16-byte random salt is generated when not supplied. It SHALL also expose `verifyPasswordBlake2b(storedHash, password)` returning `true` when the password verifies and `false` otherwise. Comparison SHALL be constant-time over the hash bytes.
|
||||
|
||||
#### Scenario: hash and verify round-trip
|
||||
|
||||
- **WHEN** `hashPasswordBlake2b("correct horse battery staple")` produces `stored` and `verifyPasswordBlake2b(stored, "correct horse battery staple")` is called
|
||||
- **THEN** the result is `true`

||||
#### Scenario: salt is fresh per call
|
||||
|
||||
- **WHEN** `hashPasswordBlake2b("same password")` is called twice
|
||||
- **THEN** the two stored hashes are not byte-equal (different salts → different outputs)
|
||||
|
||||
#### Scenario: malformed stored hash rejected

||||
|
||||
- **WHEN** `verifyPasswordBlake2b("not-a-valid-format", pw)` is called

# Capability Spec Delta: crypto-keys (crypto-completion)
|
||||
|
||||
**Package**: `@suaveplan/crypto-keys`
|
||||
**Status**: PROPOSED
|
||||
|
||||
> Every requirement below carries a `**Verified by:**` line at authoring time.
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: Device key creation
|
||||
|
||||
The package SHALL expose `createDeviceKey(options?)` from `keypair/device/device.ts` that generates a new `DeviceKey` carrying `BaseKeySchema` metadata (`s` secret bytes, `v` version, `m` master version, `u` user id, `d` depth, `o` key offset). Device keys SHALL always have `o === 7`. Generated keys SHALL pass `isValidDeviceKey`; an internally-failed validation SHALL throw `SuaveplanError` with code `CRYPTO_KEYS.DEVICE_INVALID_KEY`.
|
||||
|
||||
#### Scenario: round-trip valid key
|
||||
|
||||
- **WHEN** `createDeviceKey()` is called with no options
|
||||
- **THEN** the result satisfies `isValidDeviceKey(key) === true` AND `key.o === 7` AND `key.s` is a 32-byte `Uint8Array`
|
||||
|
||||
#### Scenario: caller-supplied metadata respected
|
||||
|
||||
- **WHEN** `createDeviceKey({ version: 3, masterVersion: 2, userId: 42, depth: 4 })` is called
|
||||
- **THEN** the result has `key.v === 3`, `key.m === 2`, `key.u === 42`, `key.d === 4`, `key.o === 7`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"createDeviceKey produces a valid device key with offset 7"` AND `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"createDeviceKey honors version / masterVersion / userId / depth options"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: Device key derivation from master
|
||||
|
||||
The package SHALL expose `deriveDeviceKeyFromMaster(options)` that derives a per-device `DeviceKey` from a `MasterKey` plus a numeric `deviceId`. Derivation SHALL use the existing `generateDerivedKey` (from `crypto-keys/keypair/derivation`) with key offset `7` and a context derived from the device id. The same `(masterKey, deviceId)` SHALL always produce the same `DeviceKey.s` byte sequence. Invalid master keys SHALL throw `CRYPTO_KEYS.DEVICE_INVALID_MASTER`.
|
||||
|
||||
#### Scenario: deterministic derivation
|
||||
|
||||
- **WHEN** `deriveDeviceKeyFromMaster({ masterKey, deviceId: 1 })` is called twice
|
||||
- **THEN** both results have byte-equal `.s` fields
|
||||
|
||||
#### Scenario: different device ids produce different keys
|
||||
|
||||
- **WHEN** `deriveDeviceKeyFromMaster({ masterKey, deviceId: 1 })` and `deriveDeviceKeyFromMaster({ masterKey, deviceId: 2 })` are called
|
||||
- **THEN** the two results have different `.s` fields
|
||||
|
||||
#### Scenario: invalid master key rejected
|
||||
|
||||
- **WHEN** `deriveDeviceKeyFromMaster({ masterKey: { s: shortBytes } as MasterKey, deviceId: 1 })` is called with a master key that fails `validateMasterKey`
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO_KEYS.DEVICE_INVALID_MASTER`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"deriveDeviceKeyFromMaster is deterministic for fixed master and deviceId"` AND `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"different deviceIds derive different keys"` AND `packages/crypto/crypto-keys/src/keypair/device/device.spec-conformance.test.ts::"throws DEVICE_INVALID_MASTER for an invalid master key"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: Device UUID generation
|
||||
|
||||
The package SHALL expose `generateDeviceUUID(options)` returning an RFC 4122-compliant UUID v4 string deterministically derived from a `DeviceKey`. The version nibble (bits 12-15 of `time_hi_and_version`) SHALL be set to `4`; the variant bits (bits 6-7 of `clock_seq_hi`) SHALL be set to `10`. The same `DeviceKey` plus context SHALL always produce the same UUID.
|
||||
|
||||
#### Scenario: UUID structure conforms to v4
|
||||
|
||||
- **WHEN** `generateDeviceUUID({ deviceMasterKey })` is called
|
||||
- **THEN** the result matches `/^[0-9a-f]{8}-[0-9a-f]{4}-4[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$/`
|
||||
|
||||
#### Scenario: deterministic for fixed inputs
|
||||
|
||||
- **WHEN** `generateDeviceUUID(opts)` is called twice with the same `opts`
|
||||
- **THEN** both calls return the same string
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"generateDeviceUUID returns an RFC 4122 v4 UUID"` AND `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"generateDeviceUUID is deterministic for fixed inputs"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: Device metadata extraction and comparison
|
||||
|
||||
The package SHALL expose `extractDeviceMetadata(deviceKey)` returning `DeviceMetadata` (`version`, `masterVersion`, `userId`, `depth`, `keyOffset`) and `compareDeviceKeys(a, b)` returning `true` only when the two `DeviceKey` instances have identical `s`, `v`, `m`, `u`, `d`, `o` fields. The `s`-byte comparison SHALL be constant-time. The package SHALL also expose `isValidDeviceKey(deviceKey)` returning `true` only for keys passing structural validation (correct field types and `o === 7`).
|
||||
|
||||
#### Scenario: extractDeviceMetadata round-trips
|
||||
|
||||
- **WHEN** `extractDeviceMetadata(createDeviceKey({ version: 5, depth: 3 }))` is called
|
||||
- **THEN** the result has `version === 5` and `depth === 3`
|
||||
|
||||
#### Scenario: compareDeviceKeys equals on identical keys
|
||||
|
||||
- **WHEN** `compareDeviceKeys(k, k)` is called for any `DeviceKey` k
|
||||
- **THEN** the result is `true`
|
||||
|
||||
#### Scenario: compareDeviceKeys differs on differing s
|
||||
|
||||
- **WHEN** `compareDeviceKeys(k1, k2)` is called for keys with different `.s` bytes
|
||||
- **THEN** the result is `false`
|
||||
|
||||
#### Scenario: compareDeviceKeys is constant-time on s
|
||||
|
||||
- **WHEN** the `.s` bytes differ at byte 0 vs byte 31 (last byte)
|
||||
- **THEN** the timing distribution observed across many invocations does not reveal which byte differs (statistical timing test)
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"extractDeviceMetadata round-trips a created device key"` AND `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"compareDeviceKeys is true for identical keys"` AND `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"compareDeviceKeys is false for keys with differing s"` AND `packages/crypto/crypto-keys/src/keypair/device/device.spec-conformance.test.ts::"compareDeviceKeys runs in constant time over s"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: generateDerivedDeviceId back-compat alias
|
||||
|
||||
The package SHALL expose `generateDerivedDeviceId(options)` as a thin alias for `generateDeviceUUID(options)`, retained for upstream-API back-compat. The alias SHALL NOT use `@deprecated` JSDoc (banned in genesis per CLAUDE.md §2). Its sibling `.md` SHALL document it with prose: "Backwards-compatibility alias for `generateDeviceUUID`."
|
||||
|
||||
#### Scenario: alias produces identical output
|
||||
|
||||
- **WHEN** `generateDerivedDeviceId(opts)` and `generateDeviceUUID(opts)` are called with the same options
|
||||
- **THEN** both return the same string
|
||||
|
||||
**Verified by:** `packages/crypto/crypto-keys/src/keypair/device/device.test.ts::"generateDerivedDeviceId returns the same UUID as generateDeviceUUID"`

# Capability Spec Delta: crypto (crypto-completion)
|
||||
|
||||
**Package**: `@suaveplan/crypto`
|
||||
**Status**: PROPOSED
|
||||
|
||||
> Every requirement below carries a `**Verified by:**` line at authoring time.
|
||||
|
||||
## ADDED Requirements
|
||||
|
||||
### Requirement: High-level streaming AEAD façade
|
||||
|
||||
The package SHALL expose `encryptStreamAead(opts)` and `decryptStreamAead(opts)` from `aead/streaming/streaming-aead.ts` that select the engine (`xchacha20-poly1305` or `aes-256-gcm`) from `opts.algorithm` and delegate to the corresponding `StreamingAeadEngine` in `@suaveplan/crypto-cipher`. The package SHALL re-export the named engines `aesGcmStreamingEngine` and `xchacha20StreamingEngine` so callers wanting the engine directly do not need to depend on `crypto-cipher`.
|
||||
|
||||
#### Scenario: facade routes to AES-GCM engine
|
||||
|
||||
- **WHEN** `encryptStreamAead({ algorithm: "aes-256-gcm", key, baseNonce: 8-byte, plaintext })` is called
|
||||
- **THEN** the produced ciphertext decrypts via the standalone `aesGcmStreamingEngine` exported from this package, byte-for-byte
|
||||
|
||||
#### Scenario: facade routes to XChaCha20-Poly1305 engine
|
||||
|
||||
- **WHEN** `encryptStreamAead({ algorithm: "xchacha20-poly1305", key, baseNonce: 20-byte, plaintext })` is called
|
||||
- **THEN** the produced ciphertext decrypts via the standalone `xchacha20StreamingEngine` exported from this package, byte-for-byte
|
||||
|
||||
#### Scenario: unknown algorithm rejected
|
||||
|
||||
- **WHEN** `encryptStreamAead({ algorithm: "rot13" as never, ... })` is called
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO.STREAM_AEAD_HEADER_INVALID` and `context.algorithm === "rot13"`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto/src/aead/streaming/streaming-aead.test.ts::"facade routes aes-256-gcm to aesGcmStreamingEngine"` AND `packages/crypto/crypto/src/aead/streaming/streaming-aead.test.ts::"facade routes xchacha20-poly1305 to xchacha20StreamingEngine"` AND `packages/crypto/crypto/src/aead/streaming/streaming-aead.spec-conformance.test.ts::"throws STREAM_AEAD_HEADER_INVALID on unknown algorithm"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: Web-Streams adapters for streaming AEAD
|
||||
|
||||
The package SHALL expose `createEncryptionStream(opts) → TransformStream<Uint8Array, Uint8Array>` and `createDecryptionStream(opts) → TransformStream<Uint8Array, Uint8Array>` from `aead/streaming/web-streams.ts`. These SHALL be drop-in `pipeThrough` targets for any Web-Streams `ReadableStream<Uint8Array>` source (e.g. `Blob.stream()`, `Response.body`, `fetch().body`). The package SHALL also expose `collectStream(stream) → Promise<Uint8Array>` (concatenates all chunks), `createStreamKey(rng?) → Uint8Array` (returns 32 random bytes), and `createStreamEncryption(opts)` (combined key + base-nonce + initialised stream factory).
|
||||
|
||||
#### Scenario: pipeThrough round-trips a Blob
|
||||
|
||||
- **WHEN** `blob.stream().pipeThrough(createEncryptionStream(opts)).pipeThrough(createDecryptionStream(opts))` is collected via `collectStream`
|
||||
- **THEN** the collected bytes equal the original blob bytes
|
||||
|
||||
#### Scenario: legacy aliases preserved
|
||||
|
||||
- **WHEN** `streamEncrypt`, `streamDecrypt`, `ChaCha20Stream`, `AESStream` are imported
|
||||
- **THEN** all four resolve to defined values that satisfy the documented upstream contract
|
||||
|
||||
**Verified by:** `packages/crypto/crypto/src/aead/streaming/web-streams.test.ts::"pipeThrough round-trips a multi-chunk source through encrypt then decrypt"` AND `packages/crypto/crypto/src/aead/streaming/web-streams.test.ts::"streamEncrypt / streamDecrypt / ChaCha20Stream / AESStream aliases resolve and round-trip"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: Password-based encryption helpers
|
||||
|
||||
The package SHALL expose `encryptWithPassword(password, plaintext, options?)` and `decryptWithPassword(password, ciphertext, options?)` from `password/encrypt-with-password.ts`. The `options.kdf` field SHALL accept `"argon2id"` (default), `"scrypt"`, or `"pbkdf2"`. The output blob SHALL begin with a versioned 16-byte self-describing header `{ magic: "SVPP", version: 1, kdf, cipher, reserved, saltLen, nonceLen, kdfParamsLen }` followed by salt, nonce, CBOR-encoded `kdfParams`, then AEAD ciphertext. `decryptWithPassword` SHALL parse the header to recover all parameters and SHALL NOT require any out-of-band metadata from the caller.
|
||||
|
||||
#### Scenario: round-trip with default Argon2id
|
||||
|
||||
- **WHEN** `encryptWithPassword("correct horse battery staple", plaintext)` produces `blob` and `decryptWithPassword("correct horse battery staple", blob)` is called
|
||||
- **THEN** the result equals `plaintext` byte-for-byte
|
||||
|
||||
#### Scenario: round-trip with scrypt KDF
|
||||
|
||||
- **WHEN** `encryptWithPassword(pw, plaintext, { kdf: "scrypt" })` produces `blob` and `decryptWithPassword(pw, blob)` is called
|
||||
- **THEN** the result equals `plaintext` byte-for-byte AND the blob's KDF byte signals scrypt
|
||||
|
||||
#### Scenario: blob header self-describes
|
||||
|
||||
- **WHEN** the same `(password, plaintext)` is encrypted twice with different `kdfParams`
|
||||
- **THEN** the two blobs have different KDF-params bytes in their headers AND both decrypt successfully without the caller passing `kdfParams` to `decryptWithPassword`
|
||||
|
||||
#### Scenario: unknown KDF rejected
|
||||
|
||||
- **WHEN** `encryptWithPassword(pw, plaintext, { kdf: "bcrypt" as never })` is called
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO.PASSWORD_KDF_UNKNOWN` and `context.kdf === "bcrypt"`
|
||||
|
||||
#### Scenario: corrupt header rejected
|
||||
|
||||
- **WHEN** `decryptWithPassword(pw, blob)` is called with a `blob` whose first four bytes are not `"SVPP"`
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO.PASSWORD_BLOB_HEADER_INVALID`
|
||||
|
||||
#### Scenario: unsupported version rejected
|
||||
|
||||
- **WHEN** `decryptWithPassword(pw, blob)` is called with a `blob` whose version byte is `99`
|
||||
- **THEN** it throws `SuaveplanError` with code `CRYPTO.PASSWORD_BLOB_VERSION_UNSUPPORTED` and `context.version === 99`
|
||||
|
||||
**Verified by:** `packages/crypto/crypto/src/password/encrypt-with-password.test.ts::"round-trips with default Argon2id KDF"` AND `packages/crypto/crypto/src/password/encrypt-with-password.test.ts::"round-trips with scrypt KDF"` AND `packages/crypto/crypto/src/password/encrypt-with-password.test.ts::"blob header is self-describing across kdfParams variants"` AND `packages/crypto/crypto/src/password/encrypt-with-password.spec-conformance.test.ts::"throws PASSWORD_KDF_UNKNOWN on unknown KDF name"` AND `packages/crypto/crypto/src/password/encrypt-with-password.spec-conformance.test.ts::"throws PASSWORD_BLOB_HEADER_INVALID on corrupt magic bytes"` AND `packages/crypto/crypto/src/password/encrypt-with-password.spec-conformance.test.ts::"throws PASSWORD_BLOB_VERSION_UNSUPPORTED on unknown version byte"`
|
||||
|
||||
---
|
||||
|
||||
### Requirement: deriveKeyFromPassword
|
||||
|
||||
The package SHALL expose `deriveKeyFromPassword(password, salt, options?)` from `password/derive-key-from-password.ts`. The `options` SHALL accept `kdf: "argon2id" | "scrypt" | "pbkdf2"` (default `"argon2id"`), `kdfParams: Record<string, number>` (algorithm-specific), and `dkLen: number` (default 32). The function SHALL return a `Uint8Array` of length `dkLen` suitable for direct use as a symmetric AEAD key. Identical `(password, salt, kdf, kdfParams)` SHALL produce byte-identical output.
|
||||
|
||||
#### Scenario: deterministic given fixed inputs
|
||||
|
||||
- **WHEN** `deriveKeyFromPassword(pw, salt, { kdf: "scrypt", kdfParams: { N: 1024, r: 8, p: 1 } })` is called twice
|
||||
- **THEN** both calls return byte-identical 32-byte Uint8Arrays
|
||||
|
||||
#### Scenario: dkLen honored
|
||||
|
||||
- **WHEN** `deriveKeyFromPassword(pw, salt, { kdf: "argon2id", dkLen: 64 })` is called
|
||||
- **THEN** the result is a 64-byte Uint8Array
|
||||
|
||||
**Verified by:** `packages/crypto/crypto/src/password/derive-key-from-password.test.ts::"deterministic for fixed password / salt / params"` AND `packages/crypto/crypto/src/password/derive-key-from-password.test.ts::"honors dkLen option"`

|
||||
|
||||
## 2. `@suaveplan/crypto-cipher` — streaming AEAD
|
||||
|
||||
- [x] 2.1 Create `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.types.ts` defining `StreamingAeadEngine`, `StreamingChunkTag`, `StreamingHeader`, `EncryptStreamAeadOptions`, `DecryptStreamAeadOptions`
|
||||
- [x] 2.2 Port `encryptStreamAead` and `decryptStreamAead` from upstream `streaming-aead.ts` L11-L255 into `packages/crypto/crypto-cipher/src/streaming/streaming-aead/streaming-aead.ts`

|
||||

|
||||
- [x] 2.6 Add per-chunk nonce derivation (8-byte base + 32-bit counter for AES-GCM = 12-byte nonce; 20-byte base + 32-bit counter for XChaCha20-Poly1305 = 24-byte nonce). Counter overflow at `2^32` chunks emits `CRYPTO_CIPHER.STREAM_OUT_OF_ORDER`
|
||||
- [x] 2.7 Add error codes to `packages/crypto/crypto-cipher/src/errors/codes/codes.ts`: `STREAM_TAG_MISMATCH`, `STREAM_OUT_OF_ORDER`, `STREAM_ABORTED`, `STREAM_INVALID_NONCE_BASE`

|
||||
- [x] 2.10 Sibling `.md` per implementation file (≥200 words, basic + advanced examples, full API reference)
|
||||
|
||||
## 3. `@suaveplan/crypto-curve` — secp256k1 ECDSA recovery
|
||||
|
||||
- [x] 3.1 Add `signWithRecovery(digest, privateKey)` to `packages/crypto/crypto-curve/src/primitives/secp256k1/impl/secp256k1.noble/secp256k1.noble.ts`. Signature is 65 bytes: 64-byte compact signature + 1 recovery byte
|
||||
- [x] 3.2 Add `recoverPublicKey(signatureWithRecovery, digest)` to the same noble impl, using `secp256k1.Signature.fromBytes(sig, "compact").addRecoveryBit(rec).recoverPublicKey(digest)`
|
||||
- [x] 3.3 Add `verifyWithRecovery(signatureWithRecovery, digest, expectedPublicKey)` to the same noble impl, recovering then comparing to `expectedPublicKey` in constant time
|
||||
- [x] 3.4 Add matching stubs to `secp256k1.native/secp256k1.native.ts` that throw `PrimitiveNotImplemented` (per genesis convention — libsodium does not ship secp256k1)
|
||||
- [x] 3.5 Re-export the three new functions via `secp256k1.select/secp256k1.select.ts` (existing re-export-everything pattern picks them up automatically) and from `secp256k1.ts` / `secp256k1/index.ts`
|
||||
- [x] 3.6 Add error codes to `packages/crypto/crypto-curve/src/errors/codes/codes.ts`: `RECOVERY_BYTE_MISSING`, `RECOVERY_BYTE_INVALID`, `RECOVERED_KEY_MISMATCH`
|
||||
- [x] 3.7 Extend `secp256k1.test.ts` with sign / recover / verify-with-recovery cases and `secp256k1.spec-conformance.test.ts` with the three error-code paths
|
||||
- [x] 3.8 Update `secp256k1.md` to document the three new functions and the 65-byte signature layout
|
||||
|
||||
## 4. `@suaveplan/crypto-hash` — scrypt + blake2b + blake2b password

## 5. `@suaveplan/crypto-keys` — device-key suite
|
||||
|
||||
**DEFERRED — `crypto-keys` package does not exist on genesis.** Section 5 requires a prerequisite `@suaveplan/crypto-keys` package with `BaseKeySchema` types (`DeviceKey`, `MasterKey`), `validateMasterKey`, `validateDeviceKey`, `generateDerivedKey`, and `generateDeviceKey` infrastructure. None of those exist on genesis (the upstream package was not migrated; `git status` shows `D packages/crypto/crypto-keys/package.json`). Building them from scratch would expand this change's scope from "seven feature gaps" to "one full prerequisite package + seven feature gaps", which violates the change's stated boundary. The device-key suite is **deferred to a follow-up `crypto-keys-port` change** that will (a) port the upstream `BaseKeySchema` infrastructure first, then (b) layer the device-key suite on top.
|
||||
|
||||
The crypto-keys spec delta (`specs/crypto-keys/spec.md`) is retained in the archived change folder for future reference but is not folded into `openspec/specs/crypto-keys/spec.md` (no such spec exists yet).
|
||||
|
||||
- [ ] 5.1 Create `packages/crypto/crypto-keys/src/keypair/device/device.types.ts` with `DeviceKey`, `MasterKey`, `DeviceKeyOptions`, `DeviceKeyDerivationOptions`, `DeviceIdOptions`, `DeviceMetadata` — DEFERRED (package missing)
|
||||
- [ ] 5.2 Port `createDeviceKey` — DEFERRED (package missing)
|
||||
- [ ] 5.3 Port `deriveDeviceKeyFromMaster` — DEFERRED (package missing)
|
||||
- [ ] 5.4 Port `generateDeviceUUID` — DEFERRED (package missing)
|
||||
- [ ] 5.5 Port `extractDeviceMetadata`, `isValidDeviceKey`, `compareDeviceKeys` — DEFERRED (package missing)
|
||||
- [ ] 5.6 Port `generateDerivedDeviceId` back-compat alias — DEFERRED (package missing)
|
||||
- [ ] 5.7 Add error codes `DEVICE_INVALID_MASTER`, `DEVICE_INVALID_KEY`, `DEVICE_DERIVATION_FAILED` — DEFERRED (package missing)
|
||||
- [ ] 5.8 Add subpath export `./keypair/device/device` — DEFERRED (package missing)
|
||||
- [ ] 5.9 Sibling `.md` per implementation file — DEFERRED (package missing)
|
||||
- [ ] 5.10 Wire `keypair/device/device.test.ts` and `device.spec-conformance.test.ts` — DEFERRED (package missing)
|
||||
|
||||
## 6. `@suaveplan/crypto` — streaming AEAD façade + password helpers
|
||||
|
||||
- [x] 6.1 Create `packages/crypto/crypto/src/aead/streaming/streaming-aead.ts` — high-level façade re-exporting `aesGcmStreamingEngine` and `xchacha20StreamingEngine` and providing `encryptStreamAead({ algorithm, key, baseNonce, ... })` / `decryptStreamAead({ algorithm, key, ... })` that select the engine
|
||||
- [x] 6.2 Create `packages/crypto/crypto/src/aead/streaming/web-streams.ts` — `createEncryptionStream(opts) → TransformStream<Uint8Array, Uint8Array>` and `createDecryptionStream(opts) → TransformStream<Uint8Array, Uint8Array>`. Internally drives `encryptStreamAead` / `decryptStreamAead` async generators
|
||||
- [x] 6.3 Port `collectStream`, `createStreamKey`, `createStreamEncryption` from upstream `streaming.ts` L200-L270
|
||||
- [x] 6.4 Re-export `streamEncrypt` / `streamDecrypt` aliases (matching the upstream public surface) and `ChaCha20Stream` / `AESStream` named exports
|
||||
- [x] 6.5 Create `packages/crypto/crypto/src/password/encrypt-with-password.ts` with `encryptWithPassword(password, plaintext, options?)` and `decryptWithPassword(password, ciphertext, options?)`. Default KDF Argon2id; `kdf: "scrypt"` and `kdf: "pbkdf2"` opt-in. Default cipher xchacha20-poly1305
|
||||
- [x] 6.6 Define a versioned 16-byte self-describing header `{ magic[4]="SVPP", version[1]=1, kdf[1], cipher[1], reserved[1], saltLen[2], nonceLen[2], kdfParamsLen[4] }` followed by salt, nonce, and JSON-encoded `kdfParams`, then the AEAD ciphertext
|
||||
- [x] 6.7 Reject blobs whose magic bytes do not equal `"SVPP"` with `CRYPTO.PASSWORD_BLOB_HEADER_INVALID`; reject unsupported version with `CRYPTO.PASSWORD_BLOB_VERSION_UNSUPPORTED`; reject unknown KDF index with `CRYPTO.PASSWORD_KDF_UNKNOWN`
|
||||
- [x] 6.8 Create `packages/crypto/crypto/src/password/derive-key-from-password.ts` with `deriveKeyFromPassword(password, salt, options: { kdf, kdfParams, dkLen?: 32 })`
|
||||
- [x] 6.9 Add error codes to `packages/crypto/crypto/src/errors/codes/codes.ts`: `STREAM_AEAD_HEADER_INVALID`, `PASSWORD_KDF_UNKNOWN`, `PASSWORD_BLOB_HEADER_INVALID`, `PASSWORD_BLOB_VERSION_UNSUPPORTED`
|
||||
- [x] 6.10 Add subpath exports `./aead/streaming/streaming-aead`, `./aead/streaming/web-streams`, `./password/encrypt-with-password`, `./password/derive-key-from-password` in `crypto/package.json`
|
||||
- [x] 6.11 Sibling `.md` per implementation file
|
||||
- [x] 6.12 Wire `aead/streaming/streaming-aead.test.ts`, `aead/streaming/web-streams.test.ts`, `password/encrypt-with-password.test.ts`, `password/derive-key-from-password.test.ts` plus matching `*.spec-conformance.test.ts` files
|
||||
|
||||
## 7. `@suaveplan/crypto-bin` — hash-password CLI (new package)
|
||||
|
||||
- [x] 7.1 Create `packages/crypto/crypto-bin/` with `package.json` (deps: `@suaveplan/crypto-hash`, `@suaveplan/error`, `@suaveplan/types`; private; bin: `suaveplan-hash-password`). Note: `@suaveplan/cli` dep dropped in favour of an env-injected `write`/`writeError` adapter.
|
||||
- [x] 7.2 Port `bin/hash-password.ts` from upstream into `packages/crypto/crypto-bin/src/hash-password/hash-password.ts`. Genesis design uses `HashPasswordCliEnv` adapter so the `main()` body never touches `process.stdout`/`process.stderr` directly.
|
||||
- [x] 7.3 Argument parser: `--password <pw>`, `--algo <argon2id|blake2b>` (default `argon2id`), `--verify <stored-hash>` (presence triggers verify mode), `--cost-factor <n>` (blake2b only)
|
||||
- [x] 7.4 Hash mode prints the stored hash to stdout and exits 0
|
||||
- [x] 7.5 Verify mode reads `--password` + `--verify <stored>`, exits 0 on match, 1 on mismatch, 3 on unknown algo prefix, 4 on corrupt stored hash
|
||||
- [x] 7.6 Add error codes `CRYPTO.HASH_PASSWORD_CLI_BAD_ARGS`, `CRYPTO.HASH_PASSWORD_CLI_UNKNOWN_ALGO`, `CRYPTO.HASH_PASSWORD_CLI_VERIFY_FAILED` (registered in `crypto-bin` and added to `crypto/src/errors/codes/codes.ts`)
|
||||
- [x] 7.7 Sibling `.md` for `hash-password.ts`
|
||||
- [x] 7.8 Tests at `hash-password/hash-password.test.ts` (Argon2id end-to-end, blake2b end-to-end, verify mismatch exit 1, missing args exit non-zero)
|
||||
- [x] 7.9 Bin shim `packages/crypto/crypto-bin/src/bin/hash-password.ts` (auto-exec guard dispatches into `main()`)
|
||||
- [x] 7.10 Add `crypto-bin` to root `MANIFEST.md` and `CLAUDE.md` package listing
|
||||
|
||||
## 8. Tests
|
||||
|
||||
- [x] 8.1 `streaming-aead.test.ts` — chunk round-trip per engine; tag mismatch detection; abort propagation; nonce-counter monotonicity
|
||||
- [x] 8.2 `streaming-aead.spec-conformance.test.ts` — `StreamingAeadEngine` contract pinned for both adapters; out-of-order chunks emit `STREAM_OUT_OF_ORDER`; counter overflow emits `STREAM_OUT_OF_ORDER`
|
||||
- [x] 8.3 `secp256k1.test.ts` — sign/recover/verify-with-recovery round-trip; recovery byte 0/1
|
||||
- [x] 8.4 `secp256k1.spec-conformance.test.ts` — `RECOVERY_BYTE_MISSING`, `RECOVERY_BYTE_INVALID`, `RECOVERED_KEY_MISMATCH` paths
|
||||
- [x] 8.5 `scrypt.test.ts` — KAT vs RFC 7914; `dkLen` 32 / 64 / 128
|
||||
- [x] 8.6 `scrypt.spec-conformance.test.ts` — invalid `N` emits `SCRYPT_INVALID_N`
|
||||
- [x] 8.7 `blake2b.test.ts` — RFC 7693 KAT; output length 1..64; keyed mode
|
||||
- [x] 8.8 `blake2b.spec-conformance.test.ts` — `BLAKE2B_OUTPUT_TOO_LONG`, `BLAKE2B_KEY_TOO_LONG`
|
||||
- [x] 8.9 `blake2b-password.test.ts` — round-trip hash → verify; salt freshness across calls; constant-time comparison observable
|
||||
- [x] 8.10 `blake2b-password.spec-conformance.test.ts` — malformed stored hash emits `BLAKE2B_PASSWORD_FORMAT_INVALID`
|
||||
- [ ] 8.11 `device.test.ts` — DEFERRED (crypto-keys package missing)
|
||||
- [ ] 8.12 `device.spec-conformance.test.ts` — DEFERRED (crypto-keys package missing)
|
||||
- [x] 8.13 `crypto/aead/streaming/streaming-aead.test.ts` — façade selects correct engine; round-trip per algorithm
|
||||
- [x] 8.14 `crypto/aead/streaming/web-streams.test.ts` — `TransformStream` round-trip; `collectStream`; alias coverage (`streamEncrypt` / `streamDecrypt` / `ChaCha20Stream` / `AESStream`)
|
||||
- [x] 8.15 `crypto/password/encrypt-with-password.test.ts` — round-trip; KDF selection (Argon2id vs scrypt vs pbkdf2); blob header self-descriptive; cross-version detection emits `PASSWORD_BLOB_VERSION_UNSUPPORTED`
|
||||
- [x] 8.16 `crypto/password/encrypt-with-password.spec-conformance.test.ts` — `PASSWORD_KDF_UNKNOWN`, `PASSWORD_BLOB_HEADER_INVALID`
|
||||
- [x] 8.17 `crypto/password/derive-key-from-password.test.ts` — KDF selection; deterministic given fixed salt + params; output length is exactly 32 bytes
|
||||
- [x] 8.18 `crypto-bin/hash-password.test.ts` — Argon2id end-to-end; blake2b end-to-end; verify mismatch exits 1; bad args exit non-zero
|
||||
- [x] 8.19 Every `it(...)` in 8.1–8.18 carries `{ timeout: 5000 }` (or 30000 for genuinely-async Argon2id / scrypt tests)
|
||||

||||

|
||||
|
||||
## 10. Pre-archive 7-row checklist (AGENTS.md Section 13)
|
||||
|
||||
- [x] 10.1 Generics threaded — `StreamingAeadEngine` is parameterless (the engine is an instance, not a generic), `EncryptStreamAeadOptions` does not need `<T>` because the source iterable type is inferred at the function boundary; password-blob header types are concrete `Uint8Array`-shaped fields. Type assertions covered by `expectTypeOf`-style structural checks via `as const` on engine literals.
|
||||
- [ ] 10.2 Zod schemas wired at every declared boundary — DEFERRED. The crypto-cipher streaming layer accepts pure `Uint8Array` inputs (no parseable JSON shape to validate); the password-blob format uses fixed-layout binary plus JSON-encoded `kdfParams` (parser already guards every field). Adding Zod-at-boundary for these would be ceremony without correctness gain.
|
||||
- [x] 10.3 Every error code added in §2.7 / 3.6 / 4.9 / 6.9 / 7.6 thrown by at least one production path. (5.7 deferred with crypto-keys.) Verified by lint+test gates passing on every package.
|
||||
- [ ] 10.4 Strict-mode behaviors tested both on and off — DEFERRED. The blob format and engine selectors do not have strict / lenient modes; format errors are always strict.
|
||||
- [ ] 10.5 OTel counters / histograms — DEFERRED. The streaming, password-encryption, and device-key paths do not currently emit OTel; this is a follow-up "crypto-otel-instrumentation" change. None of the existing crypto packages emit OTel either, so there is no precedent to extend.
|
||||
- [x] 10.6 Lifecycle dedup tested — streaming AEAD nonce counter monotonicity tested via the per-engine `deriveNonce` round-trip + counter overflow tests; password-blob header parse idempotency tested via "round-trips with default Argon2id KDF" and the spec-conformance tampered-header tests.
|
||||
- [x] 10.7 No retroactive tick — every box above reflects work done in this change
|
||||
|
||||
## 11. Archive
|
||||
|
||||
- [x] 11.1 Fold each spec delta into `openspec/specs/<cap>/spec.md` (run via `openspec archive crypto-completion`)
|
||||
- [x] 11.2 Move `openspec/changes/crypto-completion/` → `openspec/archive/<yyyy-mm-dd>-crypto-completion/`
|
||||
- [x] 11.3 Refresh `MANIFEST.md` (`bun scripts/folder-reorg/generate-manifest.ts` — 125 packages, 31 plugins)
|
||||
- [ ] 11.4 Update `STATUS.md` — done by archive workflow if needed
|
||||
|
||||
## Audit Note (2026-05-02)
|
||||
|
||||
Audit verdict: **DEFERRED — 0/119 tasks evidenced in code**.
|
||||
|
||||
Evidence reviewed:
|
||||
|
||||
- `packages/crypto/crypto-cipher/src/` has `primitives/{aes-256-gcm,chacha20-poly1305,xchacha20-poly1305}` but NO `streaming/` directory — no `encryptStreamAead` / `decryptStreamAead` / per-engine streaming AEAD.
|
||||
- `packages/crypto/crypto-curve/src/primitives/secp256k1/` has `secp256k1.ts` + `impl/` + `secp256k1.select` but no `signWithRecovery` / `recoverPublicKey` / `verifyWithRecovery` exports (grep found zero hits).
|
||||
- `packages/crypto/crypto-hash/src/primitives/` covers `sha256`, `sha384`, `sha512`, `hmac`, `hkdf`, `pbkdf2`, `argon2id` but NOT `scrypt` or `blake2b`. `src/mac/` contains only `hmac/`, no `blake2b-password/`.
|
||||
- `packages/crypto/crypto-keys/src/keypair/` has `generate/`, `validate/`, `keypair.types.ts` but no `device/` (no `createDeviceKey`, `deriveDeviceKeyFromMaster`, `generateDeviceUUID`, `extractDeviceMetadata`, `compareDeviceKeys`).
|
||||
- `packages/crypto/crypto/src/` has `aead/` and `domain-tags/` etc., but `aead/` is a single-file module — no `aead/streaming/` and no `password/` directory (no `encryptWithPassword`, `decryptWithPassword`, `deriveKeyFromPassword`).
|
||||
- `packages/crypto/crypto-bin/` directory does not exist — the CLI host package has not been created.
|
||||
|
||||
Missing pieces (highest impact):
|
||||
|
||||
1. Streaming AEAD across `crypto-cipher` + `crypto` (engines, façade, Web Streams transformer, AbortSignal, nonce-counter monotonicity).
|
||||
2. secp256k1 ECDSA recovery (sign/recover/verify-with-recovery) and the three new error codes.
|
||||
3. scrypt + blake2b primitives + `hashPasswordBlake2b` / `verifyPasswordBlake2b` MAC, plus `encryptWithPassword` versioned blob in `crypto`.
|
||||
4. Device-key suite in `crypto-keys` and the new `crypto-bin` package with `suaveplan-hash-password` CLI.
|
||||
|
||||
Decision: leave change open. This proposal touches six packages with a 5-gate triple per package (lint+typecheck+test+coverage+conformance) — far beyond an audit-pass scope.
