Lua Ciphers

Welcome to Lua Ciphers! This is an educational project where I explore and implement commonly used ciphers in Lua. There is no one real goal of this project, other than the fact it was purely educational for me.

Project Overview

In this project, you'll find implementations of various ciphers, including to:

• Caesar Cipher: A simple substitution cipher where each letter in the plaintext is shifted a certain number of places down the alphabet.
• Vigenère Cipher: A method of encrypting alphabetic text by using a simple form of polyalphabetic substitution.
• Affine Cipher: A type of monoalphabetic substitution cipher where each letter in an alphabet is mapped to its numeric equivalent, encrypted using a simple mathematical function, and converted back to a letter.
• ROT13 Cipher: A special case of the Caesar Cipher where each letter is shifted by 13 places in the alphabet.
• Rail Fence Cipher: A transposition cipher that writes the plaintext in a zigzag pattern across multiple "rails" and then reads off each row to create the ciphertext.
• Monoalphabetic Substitution Cipher: A cipher where each letter of the plaintext is replaced by a letter with a fixed relationship to it in the alphabet. The key is a permutation of the alphabet.

Getting Started

To get started with the project, you'll need to have Lua installed on your machine. You can download Lua from the official website.

Clone the repository to your local machine in your project directory:

git clone https://github.com/selectr4u/lua-ciphers.git
cd lua-ciphers

And then you can require the ciphers in your project!

local ciphers = require 'ciphers.ciphers'

Contributing

Feel free to contribute any other ciphers!
