Previously, it was not possible to use sha1sum test.c | sha1sum -c because the program would not differenciate between an empty argument and a non-specified argument. Moreover, why not allow this? sha1sum -c hashlist1 hashlist2 Digging deeper I found that using function pointers and a modification in the crypt-backend might simplify the program a lot by passing the argument-list to both cryptmain and cryptcheck. Allowing more than one list-file to be specified is also consistent with what the other implementations support, so we not only have simpler code, we also do not silently break if there's a script around passing multiple files to check.
