Pbkdf2Mb

Fast BIP-39 seed derivation (PBKDF2-HMAC-SHA512, salt "mnemonic", 2048 iterations, 64-byte seed) with native multi-buffer SIMD (AVX-512 / AVX2 / SSE2, runtime-dispatched) and an internal pinned worker pool: one call derives a whole batch across all cores. Bit-exact with Rfc2898DeriveBytes.Pbkdf2, ~4× faster per core, and ~2.6× the throughput of managed Parallel.ForEach over the same kernel.

Native libraries for linux-x64 and win-x64 are bundled and resolved automatically — no setup call, no manual file copying.

using Pbkdf2Mb;

// Pack mnemonics once into a contiguous blob + spans (reuse the buffers).
var (blob, spans) = Pbkdf2.PackMnemonics(mnemonics);     // string[] -> blob + spans

// One native call derives every seed on all cores; threads are pinned internally.
var seeds = new byte[spans.Length * 64];
Pbkdf2.DeriveSeeds(blob, spans, seeds);                  // salt "mnemonic", 2048, 64
// seed i is seeds[i*64 .. (i+1)*64)   (written in place, zero-copy)
  • DeriveSeeds(...) — Span-based, zero-copy, zero-alloc, one call for the whole batch. Pass a non-empty salt for a shared "mnemonic"+passphrase; threads: 0 (default) uses all cores.
  • PackMnemonics(...) — jagged UTF-8 mnemonics → one blob + spans (do this once).
  • Pbkdf2.Calibrate() / Pbkdf2.ForceBackend(...) — per-host tuning / pin a backend.
  • Pbkdf2.ActiveBackend, NameOf(...), IsAvailable(...) — introspection.
  • Pbkdf2.PoolShutdown() — release the pinned pool (optional; recreated on next use).

All parallelism and core-pinning live in native code, so there is no managed thread pool and no per-item marshalling. x86-64 only.
