b3sum

Command line utility for calculating BLAKE3 hashes. It is similar to Coreutils tools like b2sum or md5sum. More information: https://github.com/BLAKE3-team/BLAKE3/tree/master/b3sum.

• Calculate the BLAKE3 checksum for a file:

b3sum {{path/to/file}}

• Calculate BLAKE3 checksums for multiple files:

b3sum {{path/to/file1}} {{path/to/file2}}

• Calculate the BLAKE3 checksum from stdin:

{{some_command}} | b3sum

• Create a file of BLAKE3 checksums:

b3sum {{path/to/file}} > {{path/to/file.b3}}

• Read and verify a file of BLAKE3 checksums:

b3sum --check {{path/to/file.b3}}
