Deterministic Random Bit Generators

HMAC DRBG (digital random byte generator, NIST)

ChaCha20-based DRBG (digital random byte generator)

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

Subset Counter-Based Pseudorandom Number Generator.

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.

SHISHUA: The fastest PRNG. A seedrandom-compatible random number generator.

Seedable pseudorandom number generator (PRNG).

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

EC cryptography

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

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