Blake2 Yet Another

The BLAKE2 cryptographic hash and message authentication code. It is implemented in pure rust, achieves the best performance without using unsafe code, and supports no_std systems.

[dependencies]
blake2ya = "1.0"

Based on benchmarks, it performs slightly better than the official C implementation of BLAKE2 at -Os, and slightly worse than -O3.

Example

BLAKE2b

let mut p = blake2ya::blake2b_params();
p.digest(64);
let mut h = blake2ya::blake2b(p);
h.update(b"abc");
let mut r = [0; 64];
h.digest(&mut r);
let e = [
    0xba, 0x80, 0xa5, 0x3f, 0x98, 0x1c, 0x4d, 0x0d, 0x6a, 0x27, 0x97, 0xb6, 0x9f, 0x12, 0xf6, 0xe9,
    0x4c, 0x21, 0x2f, 0x14, 0x68, 0x5a, 0xc4, 0xb7, 0x4b, 0x12, 0xbb, 0x6f, 0xdb, 0xff, 0xa2, 0xd1,
    0x7d, 0x87, 0xc5, 0x39, 0x2a, 0xab, 0x79, 0x2d, 0xc2, 0x52, 0xd5, 0xde, 0x45, 0x33, 0xcc, 0x95,
    0x18, 0xd3, 0x8a, 0xa8, 0xdb, 0xf1, 0x92, 0x5a, 0xb9, 0x23, 0x86, 0xed, 0xd4, 0x00, 0x99, 0x23,
];
assert_eq!(r, e);

BLAKE2s

let mut p = blake2ya::blake2s_params();
p.digest(32);
let mut h = blake2ya::blake2s(p);
h.update(b"abc");
let mut r = [0; 32];
h.digest(&mut r);
let e = [
    0x50, 0x8c, 0x5e, 0x8c, 0x32, 0x7c, 0x14, 0xe2, 0xe1, 0xa7, 0x2b, 0xa3, 0x4e, 0xeb, 0x45, 0x2f,
    0x37, 0x45, 0x8b, 0x20, 0x9e, 0xd6, 0x3a, 0x29, 0x4d, 0x99, 0x9b, 0x4c, 0x86, 0x67, 0x59, 0x82,
];
assert_eq!(r, e);
