xero/leviathan-crypto

Post-quantum WASM cryptography. Authenticated encryption, signatures with key agreement, transparency logs, and ratcheting built on constant-time bitsliced ciphers (Serpent, XChaCha20, AES), post-quantum schemes (ML-KEM, ML-DSA, SLH-DSA), BLAKE3 and SHA-family hashing, and the Fortuna CSPRNG. Zero dependencies, tree-shakeable, side-effect-free.
