A Quantum computer based CSPRNG, written in python, as a PoC for using QCs in services.

A Rust Library For Generating Large Composite, Prime, and Safe Prime Numbers

Auditable CSPRNG-backed credential generator for AI agents and machine-readable pipelines. Stable JSON schema, NIST entropy floors, SLSA 3 + cosign signed releases. CLI, Go/Python/Rust libs, MCP server.

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.
