About b3sum
Command-line implementation of the BLAKE3 cryptographic hash function. Prints the BLAKE3 hashes of files or of standard input.
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.
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.
