Deterministic random bit generator (hmac)

Deterministic Random Bit Generators

HMAC DRBG (digital random byte generator, NIST)

The sealed exam's core: HMAC-DRBG, seed, paper derivation, and the two BitGraph positions (paper fused under trailer/1, answers recorded).

ChaCha20-based DRBG (digital random byte generator)

Post-quantum-only cryptographically secure random number generator. A reseedable SP 800-90A-style DRBG built on the SHAKE256 XOF (FIPS-202) — the same Keccak sponge that underpins ML-KEM/ML-DSA — with an optional ML-KEM (FIPS-203) lattice entropy-conditio

This repository implements a cryptographically secure Random Number Generator (RNG) built on **HMAC-DRBG** (Deterministic Random Bit Generator).

Subset Counter-Based Pseudorandom Number Generator.

Official client for the Sonicium Entropy API: quantum-seeded random bytes, attested reseed material and post-quantum keypairs, with offline attestation verification.

GOST cryptography algorithms in pure TypeScript

Access Arweave through Metamask

The sealed exam's public item bank: five template families, deterministic generators, checkers, and the bank digest.

EC cryptography

Temporal Hardening Solution: a multi-source CSPRNG wrapper that remains secure when individual entropy sources are compromised, backdoored, or actively hostile.

Browser entropy SDK. Harvests randomness from pointer, keyboard and sensor activity, folds it with the platform CSPRNG, and emits a verifiable audit receipt. Zero network calls.
