Post-Quantum Cryptography Playground
Explore the three NIST-standardized post-quantum cryptography algorithms interactively. See how they work step by step, from key generation to encryption and signing.
ML-KEM
Module-Lattice-Based Key Encapsulation Mechanism
Key exchange based on the hardness of the Module Learning With Errors problem. Visualize lattice points, noise vectors, and polynomial ring operations.
ML-DSA
Module-Lattice-Based Digital Signature Algorithm
Digital signatures using Fiat-Shamir with Aborts. Watch the commitment-challenge-response protocol with rejection sampling.
SLH-DSA
Stateless Hash-Based Digital Signature Algorithm
Hash-based signatures with Merkle trees. Click on tree nodes to understand authentication paths and why hash-based crypto is quantum-safe.
Algorithm Comparison
Compare key sizes, security assumptions, and tradeoffs across all three standards side-by-side.
