re how to the disks copy protected in article rcstage urc tue nl rcstage urc tue nl guido klemans writes stuff about hardware keys if you put another computer on the port instead of the key you can hack them by reading what happens so i ve been told i ve never seen this done but i think it s possible you d need some hardware knowledge and some software to read the port true which is why many of the newer keys ship out oh maybe bits or so have the key encrypt them and return them to the pc making a bunch of these bits part of your program code is a good way to make sure things won t run without the key anyway then this scheme at least defeats your approach it s a little costly though personally i don t believe in copy protection and agree with the thought that the mass inconvenience that it causes all legal users far outweighs the gains from what few pirates won t be able to copy the program joel kolstad
