as a result, the Gnu version does not support blake2s (for smaller
digests) and blakes2bp for higher performance on multicore systems.
Yes, I know about Blake3, but there are many reasons to support older
hash algorithms.
The real problem is that you have co-opted the b2sum binary so that the
testing required to find out if is system's b2sum application is the
open source b2sum from https://www.blake2.net/ or the Gnu coreutils. I
am hopeful that a similar problem is not introduced with a coreutils
version of b3sum? Will you implement the C language single thread
version (lower performance) or the parallel merkle tree rust implementation?
Since you introduce incompatible differences in the implementation, the
least that you could do is to rename the Gnu Coreutils b2sum to gnub2sum
so that applications that require different command line semantics do
NOT Have to go through machinations to find all installed versions of
b2sum on a system in order to select the correct invocation semantics.
Just my $0.02 worth, but I am trying to rationalize the world of
cryptographic hash algorithms. I have two blogs that reference this on
linkedin ( * & ** ) so that you can understand part of the reason why
this will become more important over time.
I realize that Gnu has a long tradition of implementing the Gnu version
of commands and that in many cases the Gnu versions have become the "de
facto" standards. However this does not happen if you don't support the
semantics of the commands that you are replacing.
I have been using Unix/Linux since 1974 (Arpanet node #6 at Urbana,
Illinois) and I would never have made the transition to Linux if there
were less semantic consistency over time.
If indeed you had implemented a superset of the Blake2 semantics, there
would be no cause for concern.

This is a preliminary version and I hope to release a second version
after further development.
