# @suaveplan/crypto-sodium

libsodium-backed engine implementations for `@suaveplan/crypto`. Provides AEAD encryption, Ed25519 signing, X25519 key agreement, sealed-box, auth-box, deterministic KDF, BLAKE2b MAC, Argon2id password hashing, and Ristretto255 group operations — all via the `libsodium-wrappers-sumo` WASM module.

## When to use this skill

- Implementing or debugging code that imports `@suaveplan/crypto-sodium`.
- The task touches: see package README.
- You need API guidance for this package's exports.

## Quick reference

```ts
import { /* see API Reference below */ } from "@suaveplan/crypto-sodium";
```

## Dependencies

Workspace dependencies: `@suaveplan/crypto`, `@suaveplan/error`

## Where to read more

This skill is intentionally short. The package's own documentation is the authoritative source — read these in order:

1. **`packages/crypto/crypto-sodium/README.md`** — overview, install, quick-start, module index
2. **`packages/crypto/crypto-sodium/src/**/*.md`** — co-located docs per implementation file (Purpose, Features, Basic + Advanced examples, full API reference, Implementation notes — all packages  ship ≥200 words per module)
3. **`packages/crypto/crypto-sodium/package.json`** `exports` map — every subpath you can import from

When the user asks an API question, read the relevant co-located `.md` first; do not answer from training-data memory.
