Although I am somewhat new to VB, I have written a program
that will encrypt values to the registry under the current user. It has a start key, so you will need to store that as
well so that when it is decrypted, it will be correct.
One of the good things about this code, is that I discovered
that there were occaisions where it would create a null value for one of the characters and that was bad!! So this code goes through and if any of the values are null, it increments the key by a value that you can set yourself, and then starts over to encrypt. You can adapt it to fit what you need. If you are interested, I can post the code.
