This is all actually very good feedback and a lot to take in and think about, I have no problems in admitting that something can be done in a better way and go back to the drawing board, I’ll admit, I don’t have much experience with neither of the methods you suggested, but a quick Google showed me a world of learning, so I have a lot of reading to do ♥️

P.s. I did read everything that was linked by u/litchralee btw and it was a very good read indeed

Now, onto the why I went for asymmetric encryption is due to the nature of the notes being files on a system rather than stored in a database, my thinking process being "I can use whatever public key I need for whatever note and decrypt them using the right private key at a later time.

Regarding the sharing, my thinking was “you give me a public key, I use it to encrypt the note, share it with you - privately or publicly - and you can use your private key to decrypt it”. Which is why there’s always an option to encrypt with a different public key than the one stored for yourself, I was imagining it just like encrypted emails work frankly. I may have gone a bit too much for overkill lol

I’ll see to implement additional encryption methods, if anything I’m all for choice and letting people decide what to use. There’s also the very selfish answer to your question btw being that… I like PGP and I made jotty mainly for myself hahahaa
