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.

Leviathan-crypto – WebAssembly cryptography library for TypeScript

AI Analysis
●●SolidWizardryBig Brain
WASM isolation prevents JIT speculation attacks on key material—clever security layer.
Strengths
- •WASM as correctness layer eliminates JavaScript timing vulnerabilities from table lookups.
- •Serpent-256 offers 32 rounds vs AES's 10-14 for conservative security margin.
- •Strictly typed TypeScript API with explicit init gates prevents misuse.
Weaknesses
- •Crypto libraries are extremely crowded—libsodium and Web Crypto API already exist.
- •Zero stars suggests no real adoption yet despite security claims.
Category
Target Audience
