step1、安装依赖

step2、使用curl命令下载BLAKE3源码包 （）

curl -L -o BLAKE3-0.3.7.tar.gz https://github.com/BLAKE3-team/BLAKE3/archive/refs/tags/0.3.7.tar.gz

step3、使用tar解压BLAKE3源码包

tar vxf BLAKE3-0.3.7.tar.gz

step4、进入BLAKE3-0.3.7目录

cd BLAKE3-0.3.7

step5、查看BLAKE3-0.3.7目录的内容

注意：BLAKE3分别用Rust和C实现。c目录中的代码就是C实现。

编译Rust实现：

cargo build --locked

编译C实现：

#!/bin/sh
