b2sum - compute and check BLAKE2 message digest
b2sum [OPTION]... [FILE]...
Print or check BLAKE2 (512-bit) checksums.
With no FILE, or when FILE is -, read standard input.
The sums are computed as described in RFC 7693. When checking, the input should be a former output of this program. The default mode is to print a line with checksum, a space, a character indicating input mode ('*' for binary, ' ' for text or where binary is insignificant), and name for each FILE.
