Investigate modern post-quantum encryption/signature options e.g. McEliece
This repo has a great gpg-like application for dealing with it; I think it wouldn't be too hard to implement in bote.
It's certainly a possibility, and if someone wrote a PR for it then I'd certainly review it :)
Before adding a new option however, we should think about whether there's a better format for Bote addresses (than just sticking the two public keys together). We should also think about the different trade-offs of the various post-quantum schemes (now that there has been significantly more research on them).
McEliece Keys are ungodly huge. From the GoldBug Encryption program a McEliece Public Key is 8.1 MB. Yeah I exported it to a text file and looked at the size myself.
