blake2b_simd

An implementation of the BLAKE2b and BLAKE2bp hash functions. See also blake2s_simd.

This crate includes:

• 100% stable Rust.
• SIMD implementations based on Samuel Neves' blake2-avx2. These are very fast. For benchmarks, see the Performance section of the README.
• Portable, safe implementations for other platforms.
• Dynamic CPU feature detection. Binaries include multiple implementations by default and choose the fastest one the processor supports at runtime.
• All the features from the the BLAKE2 spec, like adjustable length, keying, and associated data for tree hashing.
• no_std support. The std Cargo feature is on by default, for CPU feature detection and for implementing std::io::Write.
• Support for computing multiple BLAKE2b hashes in parallel, matching the efficiency of BLAKE2bp. See the many module.

Example

``` use blake2b_simd::{blake2b, Params};

let expected = "ca002330e69d3e6b84a46a56a6533fd79d51d97a3bb7cad6c2ff43b354185d6d\ c1e723fb3db4ae0737e120378424c714bb982d9dc5bbd7a0ab318240ddd18f8d"; let hash = blake2b(b"foo"); asserteq!(expected, &hash.tohex());

let hash = Params::new() .hashlength(16) .key(b"The Magic Words are Squeamish Ossifrage") .personal(b"L. P. Waterhouse") .tostate() .update(b"foo") .update(b"bar") .update(b"baz") .finalize(); asserteq!("ee8ff4e9be887297cf79348dc35dab56", &hash.tohex()); ```
