So I have a new email encryption system which requires that the user has the specific key file generated for a message rather than the password, specifically this software generates a unique key file for a specific message every time a message is created. The user then enters the date and time the message was created. Without the original key file the message can't be opened;

Here is a video showing the software. I've built it for Windows and Mac OS. I was wondering if this could be implemented in tor. I think it would be an interesting idea for a tor based email system to make the messages unrecoverable after use.

OS: Windows, Mac OS

What do you think?
