This idea is interesting but who owns all the keys?
Thanks and regards!

Well, the mechanism is that it overwrites the key ever time, so each message has its own unique key, also the receiver needs to verify the key file with the built in tool to be able to use it. So an attacker does not know this the only way to get this information is from the person that created the message as the need when the OS originally generated the message, not when it was uploaded as an attachment somewhere. That's what I was thinking. I will look into the communities suggested, thanks very much. --Keifer

Hi there,
Hello,
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.
I'm not a tor-dev, so I can't comment on the interest, but it appears to me that the value added of this idea (basically, using time to seed a PRF/KDF) is very little. All in all, using time to seed keys is not the best idea. It also seems to be on top of PGP, so I'm pretty convinced this doesn't provide perfect forward-secrecy unless you're layering any sort of session key ratcheting mechanism yourself.
I think the goal is laudable, but I suggest getting a little bit more involved in cryptography engineering communities to see learn, develop and eventually help change the status quo.
