This subprogram is the implementation of BLAKE3 for Quicker by Poto.

BLAKE3 designed to be fast

How to use?

input your file path list and get the corresponding sequence of hashes.

You can use either a text variable or a list variable to store the hashes, depending on how you plan to use them.

BLAKE3 is a cryptographic hash function that is:

Much faster than MD5, SHA-1, SHA-2, SHA-3, and BLAKE2.

Secure, unlike MD5 and SHA-1. And secure against length extension, unlike SHA-2.

Highly parallelizable across any number of threads and SIMD lanes, because it's a Merkle tree on the inside.

Capable of verified streaming and incremental updates, again because it's a Merkle tree.

A PRF, MAC, KDF, and XOF, as well as a regular hash.

One algorithm with no variants, which is fast on x86-64 and also on smaller architectures.

The chart below is an example benchmark of 16 KiB inputs on a Cascade Lake-SP 8275CL server CPU from 2019. For more detailed benchmarks, see the BLAKE3 paper.

BLAKE3 is based on an optimized instance of the established hash function BLAKE2 and on the original Bao tree mode. The specifications and design rationale are available in the BLAKE3 paper. The default output size is 256 bits. The current version of Bao implements verified streaming with BLAKE3.

The blake3 Rust crate, which includes optimized implementations for SSE2, SSE4.1, AVX2, AVX-512, NEON, and WASM, with automatic runtime CPU feature detection on x86. The rayon feature provides multithreading.

The b3sum Rust crate, which provides a command line interface. It uses multithreading by default, making it an order of magnitude faster than e.g. sha256sum on typical desktop hardware.
