Even though in the grand scheme of things, I suck at this and probably got all of the politically correct terms incorrect, I tried, and that's what counts!

Yes that's right, encryption! Introducting, Starlight's HXA2! HXA (Huffman XOR Addition) is a project of mine and I wanted to introduce the latest version to the public. Feel free to require() it (since it's a PrivateModule).

require(357989120)
-->Returns a small library

Try these functions with print():
Info() --Prints a bunch of documentation in the output. The stupid thing isn't in the same font as the script window so it might look warped. I made it as bearable as possible for now.
Enc("Hello world! This is Stanley calling! #Anon","MyKey!",true) --Encrypts Hello world! with MyKey! and turns on verbosity. Hold onto your seat, it's gonna get loud (and complicated) in the output.

Dec(CIPHERTEXT_FROM_ABOVE,'MyKey') --Attempts to decrypt ciphertext with incorrect key, which will return a honeyed message. Why honeyed? Because it's like a honeypot but with table indices.

Tell me what you think in the comments below!

Why not just use private modulescripts instead of encrypting anything? :o

Well here's more information, in case that's the issue:

This method can encrypt and decrypt the string "Hello world!" using the key "mykey" in 0.02 seconds with the block size root (param. 4 of 'Enc' and 'Dec') set to 16. It can take any positive integer as this value, but make sure you know it's the square root of the keystream length.

Here's the output when I input the following command (VERY LONG due to the key multiplier):

> x = require(game.ServerScriptService.MainModule); print(x.Enc("Hello world!","mykey",true))
Encrypting String:
Hello world!
Key:
mykey

o

this seems cool - ill probably look into it when i need to


speaking of encryptions=== im probably going to have to make one myself, as i am sending data from a roblox server and passing it to a JS file, and this 'data' is VEYR VERY VERY VERY VERY VERY precious and i will not allow scrubs to see it

Just use this one! The thing about it is that, to brute force it, you'd have to solve the keyblock...and good luck with 1.7*10^308 combinations. The most anyone can do is attack your passwd if all they have is the ciphertext. I'm working on a way to crack my own cipher, but it hasn't worked yet lol

But flood has.

"Well, it's software encryption so that's the deal lol"

In the real world this type of encryption would not fly by at all, and especially since checkplate is correct. You'd be able to see what's going on, including the key. Alas it's only Roblox and not a bank so who cares. Pretty cool though, but if I was to encrypt my data and store it somewhere on Roblox's server I would come up with a more obtuse method that only I know because I don't trust your library. It's a security thing, nothing personal. What's to stop you from adding some sort of backdoor on it?

Well I suppose it's all a ruse and I'm just putting your code in with my public-key type modifier that I can undo at any time...

...But here, have some source code:

https://raw.githubusercontent.com/Starlight-Inc/StarFire-Intracomm/master/HXA2_Source

*never had to personally utilize github before*

Oh, and I separated the massive tables out of that main body. Trust me you don't want to scroll through that lol. But they're on there too, close by.

Yeah I just realized that you have absolutely no way of knowing what it is. So there's the main library that's returned by the module. There are three tables left out due to sheer size, but they're in the repository as well.

To crack the code:

You know what, that's exactly what I'm gonna do.

And it isn't /no/ wait; it's minimal wait. I have a nested loop that runs without waiting, but a buffer loop to allow it room to breathe so it doesn't just freeze.
