ENCRYPT LISP?

I recently saw an advertisement for a program which is capable of encrypting AUTOLISP files. How reliable is it? Assuming AUTOCAD can understand these programs even after encrypting, can ACAD work with either, the standard kind and the encrypted, and within the same editing session? Is a memory resident program required? If so, how much memory does it require? Is there an execution speed penalty?

Len- I think I saw the same add and I think that program is basically a rip off (either intentional or not) of Autodesk's own Kelvinator. What these programs do is replace the variable names with nonsense names and remove all the carriage returns, spaces, and tabs. What results is unreadable but executable code. You can still break it if you really try. As for speed, the encrypted code may actually load and execute a little faster as it's size is reduced. I think they still give out the Kelvinator for free on request. Drop a line to Jamie or to SYSOP and see what happens! I'd definately try this route before paying for a program that appears to do the exact same thing! >>> John <<<

Was the product ENCODE? I have heard of that but haven't seen the package yet. Where did you see the article/ad ? Jamie
