gpgparticipants-prefill — insert checksum-digits in a gpgparticicpants' form


gpgparticipants-prefill [Options] EMPTYLIST FILLEDLIST


gpgparticipants-prefill takes a file produced by gpgparticipants (EMPTYLIST) and tries to fill in some digits into the SHA256 field such that the resulting list actually has a SHA256 checksum that starts with those digits.  In other words, it tries to produce a file that hashes to a checksum that is partially written down in the file. Whenever a match is found, a file with the digits filled in is written to FILLEDLIST.DIGITS.
