Wraps the keccak256 symbol exported by luxcpp/crypto/keccak. The C-ABI header is luxcpp/crypto/include/lux/crypto/keccak.h. The body is a first-party Keccak Reference v3.0 implementation with the Ethereum padding byte 0x01 (NOT FIPS 202 SHA3-256, which uses 0x06).

Use

use lux_crypto_keccak::hash;

let digest = hash(b"abc");

Build

The build script discovers libkeccak.a and libkeccak_cpu.a in the order:

CRYPTO_DIR environment variable (install prefix; archive at $CRYPTO_DIR/lib/keccak/).
CRYPTO_BUILD_DIR environment variable (cmake build dir; archive at $CRYPTO_BUILD_DIR/keccak/).
Default fallback to ../../../../luxcpp/crypto/build-cto/keccak/.

CRYPTO_BUILD_DIR=/path/to/luxcpp/crypto/build-cto cargo build --release

Test vectors

tests/spec_vectors.rs covers the standard reference vectors (empty input, "abc", "The quick brown fox jumps over the lazy dog", a million 'a' bytes, sponge-rate boundary cases). All vectors are independently verified against eth_hash (PyPA) and the keccak.team reference.
