# @suaveplan/crypto

Universal cryptographic primitives — engine-pluggable AEAD, Ed25519/ECDSA-P256 signing, X25519 key agreement, sealed-box, and auth-box. Built on audited [@noble/*](https://paulmillr.com/noble/) libraries with zero WASM.

## When to use this skill

- Implementing or debugging code that imports `@suaveplan/crypto`.
- 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";
```

## Dependencies

Workspace dependencies: `@suaveplan/crypto-cipher`, `@suaveplan/crypto-curve`, `@suaveplan/crypto-hash`, `@suaveplan/crypto-utils`, `@suaveplan/error`, `@suaveplan/types`

## 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/README.md`** — overview, install, quick-start, module index
2. **`packages/crypto/crypto/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/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.
