Secure messaging.
Post-quantum hardened.
Hybrid X25519 + ML-KEM-768 key agreement. Signal Double Ratchet for per-message forward secrecy. The server routes ciphertext only — it never sees your plaintext or contacts.

ML-KEM-768 + X25519
NIST FIPS 203 PQC algorithm hybridized with classical ECDH
Double Ratchet
Per-message key rotation — past and future messages stay protected
Zero-knowledge relay
Server stores only encrypted blobs, no plaintext in transit or at rest
