Post-Quantum Resistant Messaging
Forward-secret messaging resistant to quantum decryption. ML-KEM key exchange for future-proof confidentiality. SLHDSA signatures. Zero metadata leakage. Deniable authentication for high-risk communications.
CipherTalk uses NIST-standardized post-quantum algorithms. Secure against both classical and quantum adversaries. Every session gets a fresh key.
Lattice-based key encapsulation mechanism (FIPS 203). Quantum-resistant key establishment. No discrete-log assumption.
Stateless hash-based digital signatures (FIPS 206). Quantum-resistant message authentication and non-repudiation.
Per-message ephemeral keys. Compromise of long-term key does not expose past message content.
Encrypted headers. Timestamp, sender ID, recipient, and message length all hidden from network observer.
Recipient cannot prove sender identity to third party. High-risk communications leave no cryptographic proof of authorship.
Optional mode for ultra-sensitive communications. Pre-shared symmetric key material for information-theoretic secrecy.
CipherTalk supports multiple modes tailored to operational security requirements. Single binary, all modes available.
