Entropy API

Production-grade randomness with provenance.

Hardware-derived entropy delivery with signed provenance, explicit fallback reporting, and post-quantum key encapsulation. Built for cryptographic key generation, secure messaging, and regulated systems.

What you get

Every draw includes provenance metadata, health checks, and transparent fallback behavior.

Hardware-derived entropy

Sourced from validated quantum backends. Each draw carries a provenance record: source class, conditioning method, entropy score, and batch identifier.

Transparent fallback

If the reservoir is depleted or quality threshold is not met, the API switches to CSPRNG fallback. Always disclosed. Never silent.

Post-quantum encryption

Optional hybrid KEM key exchange (X25519 + ML-KEM-1024) with ML-DSA-65 signatures. NIST FIPS 203 / FIPS 204 compliant.

Web3 gateway

Non-custodial entropy for wallets, dApps, and on-chain protocols. Quantum-safe seeds with signed provenance per draw.
