About:
b3sum is the official command-line tool for the BLAKE3 cryptographic hash function. It provides extremely high performance with parallel processing capabilities, making it significantly faster than traditional hashing tools like sha256sum while maintaining strong security. The tool is designed for verifying file integrity and creating checksums efficiently.
Key Features:
  • Parallel hashing for maximum speed
  • Official BLAKE3 reference implementation
  • Compatible with standard checksum file formats
  • Cross-platform support
Use Cases:
  • Verifying large file downloads and archives
  • Creating secure checksums for data integrity verification
  • Comparing file contents quickly
Alternatives:
  • sha256sum – Standard SHA-256 tool, much slower but more widely available
  • b2sum – BLAKE2 hashing tool, predecessor to BLAKE3 with lower performance
