A simple version would be to simply convert the person's name to ASCII, such as: "tedd" would generate: 116 101 100 100 You can complicate this process as much as you wish -- such as, taking every other letter and multiplying it by two rendering: 232 200 And, adding 23 to the result of each: 255 223 and so on. It's really simple for you to compute and hard for them to figure out what you have done. For example, in the above example, if I wanted to register my software -- you would give me the code of: Name: tedd Registration: 255223 The name and registration could be stored in the resources OR in a preference file -- your choice. The point is if everything matches, then everything works. tedd -- http://sperling.com
