Module auth 

Cryptographic identity for Joy’s Trust Model.

Auth provides passphrase-derived Ed25519 identity keys using Argon2id for key derivation. This is the Trustship pillar of AI Governance: it answers “who is this?” with cryptographic proof rather than self-declaration.

Key hierarchy:

Passphrase + Salt --[Argon2id]--> DerivedKey --[Ed25519]--> IdentityKeypair

Modules

derive

Argon2id key derivation from passphrase and project-bound salt.

session

Session management for authenticated Joy operations.

sign

Ed25519 identity keypair for signing and verification.

token

Per-delegator AI delegation tokens with dual signatures (ADR-023).
