NAME
       b2sum - compute and check BLAKE2	message	digest

SYNOPSIS
       b2sum [OPTION]... [FILE]...

DESCRIPTION
       Print or	check BLAKE2 (512-bit) checksums.

       With no FILE, or	when FILE is -,	read standard input.

       -b, --binary
	      read in binary mode

       -c, --check
	      read BLAKE2 sums from the	FILEs and check	them

       -l, --length
	      digest  length  in  bits;	 must  not  exceed the maximum for the
	      blake2 algorithm and must	be a multiple of 8

       --tag  create a BSD-style checksum

       -t, --text
	      read in text mode	(default)

       -z, --zero
	      end each output line with	NUL, not  newline,  and	 disable  file
	      name escaping

   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

       --help display this help	and exit

       --version
	      output version information and exit

       The sums	are computed as	described in RFC 7693.	When checking, the in-
       put 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.

       Note:  There  is	no difference between binary mode and text mode	on GNU
       systems.
