Re: modifying registry with bgt

12 is right. You should never use ephemeral keys on data that isn't ephemeral. Cryptography isn't designed to be that way. If the key is lost, the data is irrecoverable. End of story. It may be possible to extract keys from BGT code, but that in no way means that, if the key changes, we will be able to decrypt your data for you. Once data is encrypted it is bound to the key that encrypted it. Its not like a password for a website where you can just change it via a simple validation email by clicking the forgot password link and get access to the data again. To alter the key that data is secured with, you first need to decrypt all the data you'd like to alter the key for, generate the new key and re-encrypt all the data. And that's how it should be.
