Enigma - Encryption API For Your Programs v4

pastebin get WYuNMxQx enigma

• Encryption/Decryption of strings
• 100% safe to your programs - no risk of corruption - if Enigma sees symbol it don't understands it simply writes it on without encryption.

--# create a new crypter
crypter =  enigma.crypt(A,B,C,a,b,c)
--# A,B,C,a,b,c are starting positions on crypter.
--# where A,B,C are numbers 1-10 that tell enigma witch out of 10 standard rotors to use and a,b,c are numbers from 1-96 that set starting positions of said rotors.
--#A,B,C can also be a valid rotor tables.Valid rotor table is table containing numbers from 1-96 in random order.

--# encrypting string
ciphertext = crypter("plaintext")

--# duplicating crypter
crypterclone = crypter.copy()

--# to decrypt create crypter with same  starting positions as one used to encrypt
decrypter =  enigma.crypt(A,B,C,a,b,c)
decrypter(ciphertext) -> "plaintext"

--# to stop crypter from being able to be copied simply add true flag at end of attributes
nocopycrypter =  enigma.crypt(A,B,C,a,b,c,true)

--# You can also stop duplication at later time by running
nocopycrypter.blockCopy()

Spoiler

--# get command line arguments
tArgs={...}

--# load the enigma API
os.loadAPI("enigma")

--# create your crypter
local crypter = enigma.crypter(1,1,1,1,1,1)

--# copy it
local crypterclone = crypter.copy()

--# crypt first argument from command line and print it
local secret=crypter(tArgs[1])
print(secret)

--# decrypt it and print decrypted
local truth = crypterclone(secret)
print(truth)

Screenshot of that program in action:

• In case of A,B,C instead of using numbers 1-10 for standard rotors you can make your own and give it instead of the number. Rotor is table containing numbers from 1-96 in random order.
• Instead of loading enigma as API you can use it as file encryption program. Simply use "enigma <absolute path> and after few quick questions selected fill will be encrypted.
• Enigma was secure at time of its creation. In this days it is easy to brute force. This program was not made to be a secure encryptor instead it is a recreation of actual enigma method of encryption.

Why would encryption for programs even be needed? All the programs made here are meant to be Open-Source only.
Passwords I would see encryption for, but this I wouldn't be able to find a use for it.
Good job on the GUIs though!

1. Because i wanted to make Working version of Enigma
2. Because people keep stealing my tree-cutting turtle
3. Because when you keep something like password for wireless communication in program then with some encrypting and regularly changed passwords you can ensure that even if someone stole your data password still is secure.
4. Because why not? Its feels nice to make something :P/>

Heh, seems a bit casual gotta love your reasons. I don't know anyone who would put their passwords into a plain-text file though haha!
You might make an invisibility cloak (you know, Harry Potter?) for your Turtle as well… someone needs to make that, so people stop stealing your turtles.

why do u need to clone the crypter, why bother to, it doesn't seem that u need to. idk

• Added sanity test to ensure most common bugs are stopped.
• Added ability to disable making copies of cypher. It can be defined when creating a cypher or at later time by running block function inside it.
• Moved the cypher state inside the secure local table. This stops outside functions for touching the state and allows the copy blocking to be secure. Also its more secure than in last version so yea.

Can we have a mathematical proof of this right now? It doesn't appear to exactly follow the original machine. Also, I'd like to see it not not churn out the same letter as the original, as that was a big issue for the original machine. That would make it less crackable! Also, what about the front board sockets? Those increased the complexity and were only issued in the military versions.

I'm going to make an encrypted decentralized chat out of this. Can you suggest a funny name for it? I'm not too good with program names.

• Fixed logic error in encryption algorithm that in edge case caused encrypted code to be corrupted.
