The official Rust and C implementations of the BLAKE3 cryptographic hash function, which is faster than MD5, SHA-2, and BLAKE2 while remaining secure. It supports SIMD parallelization, multithreading, verified streaming, incremental updates, and doubles as a PRF, MAC, KDF, and XOF.

Use cases

• compute fast cryptographic hashes of files
• replace sha256sum with a faster checksum tool
• derive keys with a KDF
• verify large files with verified streaming hashes
• hash data incrementally in a Rust or C application
• implement MACs or PRFs in a security-sensitive project

When to choose

• you need maximum hashing speed with SIMD and multithreading
• you want a modern hash function immune to length-extension attacks
• you need verified streaming or incremental hashing via a Merkle tree
• you want one algorithm that works well across x86-64, ARM, and WASM

When to avoid

• you need password hashing specifically - use Argon2 or a dedicated password hasher instead
• you must interoperate with systems that only support SHA-2 or SHA-3
• you need FIPS-validated cryptography
