Hi there, I'm trying to create a program/library that lets me understand how encryption works. I may plan to add an entire encrypted file format.

⚠️⚠️DISCLAIMER⚠️⚠️: this library isn't meant to be used in any harmful way, so if it will be used in such a way, it's not my fault.

ROADMAP:

• Undestand how encryption works (ish)
• Create a file/library that lets me encrypt messages with a key
• Use the library/file to encrypt a file
• Create a file format that contains other files that are encrypted (ex.: encrypted zip-files)

I've recently come to an error: if you try to feed into the program characters such as "è", it will spit out a sequence of 2 hexadecimal numbers that are not correct. I believe it has something to do with the Lua function string.byte(), because it gives back a value of 195 instead of a value of 232. Please, try to find why it happens, cause I'm really struggling to find an answer.

Update about the previous issue: I believe that Lua translates these kinds of characters to two characters, but it translates them back to their original form when you use string.char(). I believe that this is an explaination of the phenomenon that is happening

Now the program lets you insert the number of times that you want it to be encrypted, therefore it should be "safer".

Thanks for your attention. ~DefinetlyNotCarl
