Things that piss me the fuck off about user programs(in this case text editors):

No fucking documentation or signs of it available, a promise from like 3 years ago to post: tutorials/actual docs and yet unfulfilled shit. Yet the author sells the editor, you can get a free version of it, but the extension api is only given in the paid version. It's like $12 bucks, which depending on where you are from is really the cost of a meal.

The editor in question is 4coder, seems like a good stack for building C/C++ based applications with a lot of cool utilities underneath, I see dudes using it to create a lot of cool shit online, but things like moving input, stopping the thing from formatting pasted code etc etc. Shit, even reaching the documentation is fucky, you get the names of the commands......ok...awesome...wtf do I do with these? Why do i need to watch a 20+ minute tutorial from the developer instead of being able to read a retarded ass tutorial regarding how to do the most basic shit? For an editor that is set to replace Emacs and Vim for developers inside of a windows platform....it sure is lacking AF in that regards.

I really want to work with this thing because it seems to be made with a lot of heart, just can't stand the fact that the documentation is lacking like a motherfucker

Noob question

Is it better to implement a cryptpgraphic algo in a function or in a class? Also how?

More info:
I have a cryptography class and I really enjoy implementing the different techniques that we study in class. At first I was just implementing the techniques in a simple function with 3 parameters; key, message and a bool for encryption or decryption. But as they are getting more complex, it is becoming harder to continue implementing them in a single function block. So I thought of using a class but ran into the problem of how do I even do that? Do I make different methods for key generation, encrypting and decrypting?

P.S. It's really just for learning how the crypto technique works and not for anything serious.
