Hash: SHA256

line 70 of the man page:

        Minting stamps

        The -m flag must be given to mint a stamp.

        The resource name (recipient's email address) to mint the stamp
        against can be passed as an argument, or if omitted is read from
        stdin.  If stdin is a tty the user is prompted, if stdin is a pipe
        the resource name is just silently read.  The desired collision
        size can be specified with the -b option.  If no collision size is
        specified, the default is 20 bits.  See also the -b default option


but this doesn't seem to do anything:
        $ echo 'abc@xyz' | hashcash -Xm

that should be sending a resource name to hashcash via stdin...

        "All censorships exist to prevent anyone from challenging
         current conceptions and existing institutions. All progress
         is initiated by challenging current conceptions, and executed
         by supplanting existing institutions. Consequently, the first
         condition of progress is the removal of censorships."
