Rust clone of the BLAKE2b checksum utility in GNU coreutils.
cargo install b2sum
``` Print or check BLAKE2 (512-bit) checksums. With no FILE, or when FILE is -, read standard input.
Usage:
b2sum [options] [
Options: -c, --check read BLAKE2 sums from the FILEs and check them -l, --length=BITS digest length in bits; must not exceed the maximum for the blake2 algorithm and must be a multiple of 8 [default: 512] --tag create a BSD-style checksum
The following five options are useful only when verifying checksums: --ignore-missing don't fail or report status for missing files --quiet don't print OK for each successfully verified file --status don't output anything, status code shows success --strict exit non-zero for improperly formatted checksum lines -w, --warn warn about improperly formatted checksum lines
-h, --help display this help and exit --version output version information and exit
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 and name for each FILE. ```
