You mean, you "tampered" with the file and the signature is still
valid? Are you sure? Then Adome does sometging really bad, IMHO.
Such a signature should ensure that the file is unmodified completely.
otherwise somebody can modify it in a way that could be used as a
backdoor to the signature, at least in theory.
