about

nx_csprng.nx -- cryptographically secure random via getrandom(2). license_tier: INDEPENDENT_REDERIVE genealogy_id: international-research-sources/nist/sp_800_90a Companion to nx_random (xoshiro256++): when caller needs entropy suitable for cryptographic keys, session tokens, AT_RANDOM seed material -- not deterministic test fixtures. Backed by the Linux getrandom() syscall (number 278 on RV64). Falls back to reading /dev/urandom if getrandom is unavailable (early boot or older kernel). API: nx_csprng_fill(dst, n) -> 0 on success, negative errno on fail nx_csprng_u64() -> i64 (full 64 bits of entropy) nx_csprng_seed_rng(rng) -> reseed an nx_random.NxRng with crypto entropy Pairs with nx_random (deterministic) + nx_uuid (entropy consumer).
