Algorithms
NIST-Standardized PQC
Quantum Cyber Safe implements the complete NIST Post-Quantum Cryptography standard, FIPS-validated and hardware-accelerated where available.
The Foundation
Built on lattice-based hardness
The hardest problems in mathematics make the strongest locks. Our core algorithms rely on the difficulty of finding the shortest vector in a high-dimensional lattice — a problem even a large-scale quantum computer cannot efficiently solve.
Module-lattice security
ML-KEM and ML-DSA derive their strength from worst-case lattice hardness.
FIPS-validated
Standardized and certified to the latest NIST PQC specifications.
ML-KEM
Key Encapsulation Mechanism based on lattice hardness. Replaces RSA and ECC key exchange. FIPS 203.
Key exchange
ML-DSA
Module-Lattice Digital Signature Algorithm. Drop-in replacement for RSA-PSS and ECDSA. FIPS 204.
Signatures
SLH-DSA
Stateless hash-based signature scheme with ultra-conservative security assumptions. FIPS 205.
Hash-based
FN-DSA
Falcon-based NTRU lattice signatures. Compact signatures for constrained environments. FIPS 206.
Compact sigs
Hybrid X25519+MLKEM
TLS 1.3 hybrid key exchange combining classical Curve25519 with ML-KEM-768 for safe transition.

AES-256-GCM
Symmetric encryption quantum-resistant at 256-bit. Grover's attack halves security; 256-bit stays safe.
