file digest
A command-line utility for calculating and verifying file checksums.
Digest is a command-line utility which can be used to calculate and verify checksums of any files, similar to md5sum or RHash, but using modern hash algorithms. Supported algorithms: BLAKE, BLAKE2, Grøstl, JH, Kupyna, MD5, SHA-1, SHA-2, SHA-3, Skein, SM3, Streebog, Whirlpool.
Usage:
digest [-c] <algorithm> <filename(s)>
For example, if you want to calculate the checksums using skein512/256 algorithm, use this command:
digest skein512/256 * > checksums.skein
