Here you will find the Perl program uncode.pl,
intended to demonstrate how canonicalization of bodies by reversing all
Content-Transfer-Encodings could lead to a more robust signature that would
still work even if Content-Transfer-Encodings within a message were altered
Also a tar file containing test data and a shell
script to run it. These files were tarred together because they contain CRs in
critical places and naked LFs in others, and I don't trust HTTP and non-Unix
operating systems not to muck them up :-( .
