Crate blakity 

blakity – a tiny, portable BLAKE3.

A #![no_std] BLAKE3 in a single file with no dependencies, derived from upstream’s reference_impl. It targets small binaries (UEFI and other no_std builds) while staying faster than the reference implementation, without SIMD intrinsics or platform-specific code.

The API is the same as upstream’s reference_impl: a Hasher for the regular hash, the keyed hash and the key derivation function, whose finalize fills an output slice of any length (the extendable output). On top of it, hash hashes a whole input at once into a [Hash], which converts to and from hex.

Examples

let hash = blakity::hash(b"abc");
let hex = "6437b3ac38465133ffb63b75273a8db548c558465d79db03fd359c6cd5bd9d85";
assert_eq!(hash.to_string(), hex);
assert_eq!(blakity::Hash::from_hex(hex), Some(hash));

let mut hasher = blakity::Hasher::new();
hasher.update(b"abc");
hasher.update(b"def");
let mut hash = [0; 32];
hasher.finalize(&mut hash);
let mut extended_hash = [0; 500];
hasher.finalize(&mut extended_hash);
assert_eq!(hash, extended_hash[..32]);

Structs

Hash

A 32-byte BLAKE3 output, as returned by hash.

Hasher

An incremental hasher that can accept any number of writes.

Functions

hash

Hashes input with the regular hash function: a new Hasher, one update and a 32-byte finalize.
