Crate clasp_crypto 

clasp-crypto

E2E encryption add-on for the CLASP protocol.

Layers

• Primitives (primitives): Pure crypto operations — AES-256-GCM, ECDH P-256, HKDF-SHA256, ECDSA P-256. No CLASP dependency.
• Protocol (protocol): E2ESession state machine for key exchange over CLASP paths.
• Storage (storage): KeyStore trait with MemoryKeyStore.
• Client (client, behind client feature): CryptoClient wrapper for transparent encrypt/decrypt over a clasp_client::Clasp instance.
