BLAKE3-c
A very rough initial implementation of BLAKE3 in C. SSE4.1, AVX2, AVX-512, and NEON are supported, using compile-time feature selection in the Makefile.
This implementation is simpler than the Rust implementation. It doesn't support multithreading, and it doesn't parallelize parent hashes, so throughput is lower.
TODO:
- CI testing for AVX-512 and NEON.
- Cross-platform build, e.g. Windows.
- Dynamic CPU feature detection, at least for x86.
Example usage:
$ make avx2
$ head -c 1000000 /dev/urandom | ./blake3
