rblake2sum

A recursive file-system blake2 digest (hash) tool.

Like sha256sum, but for directories, and using blake2.

The recursive file-system algorihtm used is described in a underlying library crev-recursive-digest.

Under the hood it uses walkdir and blake2, with an efficient IO handling, which makes it fast.
