account_cryptographic_state.rs

//! User account cryptographic state
//!
//! This module contains initialization and unwrapping of the user account cryptographic state.
//! The user account cryptographic state contains keys and cryptographic objects unlocked by
//! the user-key, or protected by keys unlocked by the user-key.
//!
//! V1 users have only a private key protected by an AES256-CBC-HMAC user key.
//! V2 users have a private key, a signing key, a signed public key and a signed security state,
//! all protected by a COSE-serialized XAES-256-GCM key.
