Ethnic Vagina Finder
The Great Paper Chaser
I think he is using AES as-is but without traditional key exchange (so independent generation) and that is the part that he has invented. Also the stuff to get around legal restrictions.
Inference by virtue of what has been proven about the libs/algs he is using (not developed).
I agree that it might be useful to get a security expert to have a look at his system.
And then another to look at his infrastructure.
it doesn't use AES at all. As previously stated, it's something I invented. Now the app does have an AES encryption tool that you can use to encrypt files on your computer. But the email feature doesn't use it. I wanted to create something that could be potentially patentable.
