b3sum

Calculate BLAKE3 cryptographic checksums. More information: https://github.com/BLAKE3-team/BLAKE3/tree/master/b3sum.

• Calculate the BLAKE3 checksum for one or more files:
  b3sum {{path/to/file1 path/to/file2 ...}}
• Calculate and save the list of BLAKE3 checksums to a file:
  b3sum {{path/to/file1 path/to/file2 ...}} > {{path/to/file.b3}}
• Calculate a BLAKE3 checksum from stdin:
  {{command}} | b3sum
• Read a file of BLAKE3 sums and filenames and verify all files have matching checksums:
  b3sum --check {{path/to/file.b3}}
• Only show a message for missing files or when verification fails:
  b3sum --check --quiet {{path/to/file.b3}}
