There are govt's out there that won't let you import code that is "encryption ready". You must prove that your software is tamper proof before it can be imported, and tamper proofing means that you can't bolt on security. Also, I believe the export laws disallow "plug in" security in the US...
Central point software faced this problem. So they made the encryption features of their product a free add on, and posted it on bulleting boards with instructions not to download unless you were an American citizen. Needless to say these instructions were ignored, surprise surprise. Of course this strategy only works if your product is useful without encryption, and the add on is of limited use without your product. I believe that Kevin Welch decided on this strategy. --------------------------------------------------------------------- We have the right to defend ourselves and our property, because of the kind of animals that we are.
