Crate anima_identity 

Anima Identity — Cryptographic Identity for Life Agents

This crate provides the cryptographic operations for agent identity:

• Seed management: Single 32-byte master seed → dual keypair derivation
• Ed25519: Agent Auth Protocol compatible authentication + JWT signing
• secp256k1: Haima-compatible wallet identity for on-chain economics
• Keystore: Unified interface for creating and managing agent identity

Key Derivation

MasterSeed (32 bytes, random)
  ├── HKDF(seed, "anima/ed25519/v1")   → Ed25519 private key
  └── HKDF(seed, "anima/secp256k1/v1") → secp256k1 private key

Both keys are cryptographically independent despite sharing a seed. The seed is encrypted at rest using ChaCha20-Poly1305.
