This Program takes an Epub you give it (please stick to legally aquired ones, I like using books from the book bundles on humblebundle because they have a lot DRM free, and same to Guttenburg press.) and parses it to turn every paragraph into a Cryptogram.

It's not perfect, and it has a few quirks which could probably be improved like sometimes adjusting around the keyboard too much, but I was just making it for myself and it's been very useful for me.

IMPORTANT: This code uses LocalStorage for the most recent file so you don't have to add a file every time. THIS IS NOT A SECURE STORAGE AREA, SO DON'T USE ANYTHING SENSITIVE!!!! It shouldn't cause any security issues, as long as you just recognize it isn't perfectly secure, and some attacks can get into it if something else gets there somehow. My goal was getting something I could play on my phone, without having to host a webapp or something.

By default, other sites shouldn't see it, I've just seen that it is still pretty insecure in terms of finding ways in.

If you find use in it or want to improve it, feel free.

This has been an ongoing project for probably a year now. Mix of vibe coded (multiple different AIs at different times) and not, features added and modified. I'm not trying to sell this as perfect software, it's just software I personally find a lot of enjoyment in.

This is probably about the 10th version or so, at time of original upload. I most recently added something in January, I think.
