My Keys System is a copy protection system for Blitz Basic v2.1 programs,
currently in it's 1.3 version, it uses Public keys created by users and
private keys made by authors.

It's really quite simple to use, a public key is made by a user and kept on
their system, when they register a program the file is sent to the
programmer and he can then create a private key which will only work on that
user's system only, and only with that program.

This insures validation of the user by the programmer, and several functions
for the program to use, allowing it to enter demo modes, report pirate
copies and so on.
