Hello Clint

Thanks for your answer to my question about this encrypted file.

Your suggestion to directly encrypt the entries seems to be a good idea. You
asked me what kind of encryption scheme I am planning to use. I have no idea
at the moment. Because I don't want to spend a lot of time I am interested
in "ready to use solution".

That's why I am looking for a simple encryption function or something like
that. It doesn't
have to be a extremly secure one. Did you heard about such a function?

Any ideas?? Let me know!
If I find a solution, I'll let you know.
Andy.
