BLAKE3¶

Module: Std::Hash::Blake3

256-bit BLAKE3 cryptographic hash.

Summary¶

struct Blake3

Blake3.Hash(message: char8[]) -> String

Constants¶

Constant	Value
`BlockSize`	64
`DigestSize`	32

Description¶

BLAKE3 is a 256-bit hash function designed in 2020 as the successor to BLAKE2. It uses a Merkle tree construction enabling parallel hashing of large inputs, with a base compression function derived from BLAKE2s (the 32-bit word variant). The algorithm applies 7 rounds of the G-function and supports incremental updates, keyed hashing, and extendable output (XOF).

BLAKE3 is cryptographically secure and significantly outperforms SHA-2 and BLAKE2 on multi-threaded platforms and large inputs.

The Hash method takes a char8[] and returns a hex-encoded digest string.

Example¶

import Std::Hash::Blake3;

func Main() {
    let digest = Blake3::Hash(c8"abc");
    PrintLine(digest);
    // 6437b3ac38465133ffb63b75273a8db548c558465d79db03fd359c6cd5bd9d85
}
