Post-quantum encryption

Secure messaging for the quantum era

End-to-end encrypted chat using hybridML-KEM-768 + X25519 key exchange andML-DSA-65 + Ed25519 signatures. The server only ever sees ciphertext.

Hybrid key exchange

Each message derives keys from both classical X25519 ECDH and post-quantum ML-KEM-768 encapsulation.

Forward secrecy

Ephemeral keys per message mean compromising long-term keys does not reveal past classical secrets.

Authenticated

Every message is signed with Ed25519 and ML-DSA-65 identity keys, verified by the recipient.
