ML-KEM-768

NIST FIPS 203 · Key Encapsulation

Replaces RSA/ECDH for quantum-safe key exchange. Shor-resistant. PubKey: 1184B · SecKey: 2400B · CT: 1088B · NIST Level 3

ML-DSA-65

NIST FIPS 204 · Digital Signatures

Replaces ECDSA/RSA for quantum-safe signing. Used for plugin signing and auth. Sig: 3309B · NIST Level 3

SLH-DSA

NIST FIPS 205 · Hash-Based Signatures

Root of trust for 313-BIND receipts. Secure even if lattice assumptions fail. PubKey: 32B · Sig: 17088B · NIST Level 5
