This is mostly used for testing/verification, like mpicalc is. I used that
to check gost hashes implementation (to compare file caches with
hashes generated by other tools). When I had several similar
test programs locally, I thought that libgcrypt can benefit from having
such standalone tool.

N/p. I got used to that in the kernel world.
