I am looking to calculate BLAKE2 hashes for files on my Ubuntu 16.04 machine. I would like something similar to md5sum or sha512sum for BLAKE2, however have not found a package in the Ubuntu repositories that provides this functionality.
It seems that the "b2sum" command is provided in coreutils version 8.26 and newer, which presumably does this, however 16.04 has verion 8.25. This functionality does not appear to be in the versions of hashdeep or hashrat in 16.04 either.
As such, I tried installing the libb2-1 package. Unfortunately it does not seem to provide the "b2sum" command (as the libdigest-sha3-perl package does with the sha3sum command).
Is there a package that provides a command I can run to obtain BLAKE2 hashes in the Ubuntu 16.04 (xenial) repositories?
