name: crypto-vault description: Use when implementing or debugging code that uses @suaveplan/crypto-vault: BIP39 mnemonic, Argon2id-locked vault, and chain signer for @suaveplan/crypto — deterministic HD key derivation, zeroize-on-lock, typed events.

@suaveplan/crypto-vault

BIP39 mnemonic management, Argon2id-hardened hierarchical key derivation, and multi-algorithm signing registry for the Suaveplan platform. The Vault class generates or imports a 12/15/18/21/24-word BIP39 mnemonic, unlocks it into a locked/unlocked state machine, derives named signing keys from HD paths (m/signing/0, m/auth/0, etc.) using either Ed25519 or ECDSA-P256, and zeroizes all key material on lock(). The ChainSigner is a standalone multi-key registry that associates named keys with signing algorithms for multi-signature workflows. Events (unlock/lock/derive/sign) are emitted via @suaveplan/events for audit trails. This package sits above @suaveplan/crypto-keys (raw keypair generation) and @suaveplan/crypto (primitive operations) — use it when you need mnemonic-seeded key hierarchies, not just raw keypairs.

When to use this skill

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

Quick reference

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

Dependencies

Workspace dependencies: @suaveplan/crypto, @suaveplan/crypto-hash, @suaveplan/crypto-keys, @suaveplan/error, @suaveplan/events, @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-vault/README.md — overview, install, quick-start, module index
2. packages/crypto/crypto-vault/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-vault/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.
