Hanzo AI d8de0bab87 crypto: PQ canonical terminology (FIPS 203/204/205 + Pulsar + Lamport) 2026-05-05 17:55:42 -07:00
Hanzo AI 935f55db81 brand-neutral: drop LUX_ prefix from env/symbols/exports 
Brand stays in import path only; symbols, env vars, and exports are
brand-neutral. One-release backwards-compat shim reads deprecated
LUX_ names with deprecation log.

Env: CRYPTO_BACKEND, CRYPTO_DIR, CRYPTO_BUILD_DIR, CRYPTO_LIB_DIR,
CRYPTO_LIB are canonical.

Rust: idiomatic Secp256k1Status enum; extern fn names dropped lux_ prefix.

TS/Python: cryptoAvailable / crypto_available; FFI symbol strings drop
lux_ prefix to match renamed C-ABI in luxcpp/crypto.

cabi/main.go: //export names drop lux_ prefix (mlkem768_*, mldsa65_*).

Hanzo AI ecaca10cdb canonical Go entry: backend selector + batch GPU paths via lux/accel 
luxfi/crypto becomes the single Go entry point for ALL Lux-family crypto.
Every public function in this module now dispatches between three
implementations through a runtime-selectable backend:

  - vanilla: pure-Go reference (always available)
  - cgo:     native binding (blst, libsecp256k1, ckzg) where present
  - gpu:     batch acceleration via github.com/luxfi/accel

The dispatcher reads LUX_CRYPTO_BACKEND (auto|vanilla|cgo|gpu); auto
picks the most capable backend the binary was compiled and linked with.

New canonical packages:
  backend/             runtime backend selector (env + programmatic)
  internal/gpuhost/    accel session lifecycle, single per-process
  keccak/              Keccak-256 with batch GPU dispatch
  sha256/              SHA-256 with batch GPU dispatch
  sha3/                SHA3 / SHAKE family
  ripemd160/           RIPEMD-160 (Bitcoin/Lux address derivation)
  ed25519/             Ed25519 with batch GPU verify
  bn254/               canonical alias for bn256 (matches FIPS naming)
  modexp/              canonical alias for bigmodexp
  evm256/              EIP-196/197 precompile ABI wrappers
  poseidon/            Poseidon2 hash via gnark-crypto
  pedersen/            Pedersen commitments over BN254
  ntt/                 Number-Theoretic Transform reference
  polymul/             negacyclic polynomial multiplication

Extended existing packages with batch GPU paths:
  bls/batch.go         BatchVerify routes through accel.BLSVerifyBatch
  mldsa/batch.go       BatchVerify (ML-DSA-65) via accel.DilithiumVerifyBatch
  mlkem/batch.go       BatchEncapsulate / BatchDecapsulate via Kyber kernels
  secp256k1/batch.go   BatchVerifySignature via accel.ECDSAVerifyBatch

GPU dispatch is gated on (a) backend.Default(), (b) batch size threshold,
and (c) accel.Available(). When any gate fails the call falls through to
the vanilla CPU path; output is byte-identical.

The legacy gpu/ stub is replaced with a thin probe surface (Available,
Backend, Devices, Version) that delegates to the same gpuhost session.

Tests show vanilla and gpu backends produce identical outputs across all
batch entry points (-race clean).

See AUDIT.md for the per-algorithm state matrix and honest gaps.
