blake2_bin

The blake2_bin crate provides the blake2 command line utility, based on the blake2b_simd and blake2s_simd implementations of BLAKE2. It supports BLAKE2b, BLAKE2s, BLAKE2bp, and BLAKE2sp.

Installation

cargo install blake2_bin

Example

```

Hash standard input, using BLAKE2b by default.

$ echo hello world | blake2 fec91c70284c72d0d4e3684788a90de9338a5b2f47f01fedbe203cafd68708718ae5672d10eca804a8121904047d40d1d6cf11e7a76419357a9469af41f22d01

Since BLAKE2b is the default, explicitly adding the -b flag gives the same result.

$ echo hello world | blake2 -b fec91c70284c72d0d4e3684788a90de9338a5b2f47f01fedbe203cafd68708718ae5672d10eca804a8121904047d40d1d6cf11e7a76419357a9469af41f22d01

Using the -s and -p flags together gives BLAKE2sp.

$ echo hello world | blake2 -sp 43958a843c00345bae4492cc04ecd1e47453469afeae277e067cad66244625eb
