I love this comment. Thank you for putting the time in to proposing a more thorough solution. I will take this (and other) comments into consideration, and make some much needed improvements :)

There are a whole bunch of things you're likely to get wrong trying to design your own "hybrid" encryption system. It's not easy. Why not spend some time learning how to break crypto before you start building it?

I agree. There are whole classes of problems that are not at all obvious until one has spent time learning how to break bad crypto. Matasano's challenges[0] (which I think tptacek helped create) are a good start.

Do you have any specific resources that you can recommend for learning to break crypto?

- Matasano crypto challenges: http://cryptopals.com/

- https://www.crypto101.io/ both the presentation and the book.

I think those are good to begin with.
