# BLAKE3-c [](https://github.com/veorq/BLAKE3-c/actions)
|
||
|
|
|
||
|
|
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](https://github.com/veorq/BLAKE3). 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:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
$ make avx2
|
||
|
|
$ head -c 1000000 /dev/urandom | ./blake3
