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.
This is free and open source software.
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.
