in reply to Re^7: Patch an old Perl version
in thread Patch an old Perl version

Learning would be reading all the publicly printed material on this attack and then using it to generate an attack key set on your own. That is what most clever people would do when someone told them "yes this is possible".

But you seem to be so stuck on your belief it can't exist that you haven't even tried. That isn't learning, nor is it challenging, it is just sad.
