The kcapi-hasher application provides tool to compute and
check the message digest as well as keyed message digest ciphers of the
Linux kernel crypto API from the command line.
The command line arguments, inputs and outputs closely mimick
those of other similar utilities. I.e. sha1sum(1)
sha512sum(1), and etc.
This is a multi-call binary, and algorithm can be selected by
symlinking this application under the desired name. Separately application
name can be overriden directly with with name option, or desired hash can be
selected with the hash option.
The input data can be provided either via STDIN or via a file that
is referenced with a command line option.
