Mathematic Overview

Key Creation

p = (10, 20)
c = (1, 2, 3, 4)
k = (
        ((((p(1) + c(1)) - c(2)) * c(3)) / c(4)),
        ((((p(2) + c(1)) - c(2)) * c(3)) / c(4))
    )

Decryption

c = (1, 2, 3, 4)
k = (6.75, 14.25)
p = (
        ((((k(1) * c(4) / c(3)) + c(2)) - c(1)),
        ((((k(2) * c(4) / c(3)) + c(2)) - c(1))
    )

Variable Definitions

• p : The variable that represents the plaintext value.
• c : The variable that represents the ciphertext value.
• k : The variable that represents the key value.

Usage

Sample Code

using System;
using System.Text;

class Program
{
    static void Main()
    {
        byte[] plaintext = Encoding.UTF8.GetBytes("My secret");
        byte[] ciphertext = Encoding.UTF8.GetBytes("Not my secret");
        byte[] key = Chug.CreateKey(plaintext, ciphertext);
        byte[] secret = Chug.Decrypt(ciphertext, key);

        Console.WriteLine("plaintext\t:\t{0}", BitConverter.ToString(plaintext).Replace("-", "").ToLower());
        Console.WriteLine("ciphertext\t:\t{0}", BitConverter.ToString(ciphertext).Replace("-", "").ToLower());
        Console.WriteLine("key\t\t:\t{0}", BitConverter.ToString(key).Replace("-", "").ToLower());
        Console.WriteLine("secret\t\t:\t{0}", BitConverter.ToString(secret).Replace("-", "").ToLower());
    }
}

Expected Output

plaintext       :       4d7920736563726574
ciphertext      :       4e6f74206d7920736563726574
key             :       432495704356add042e2b331434fd909433fe88c433da1a0434eb592433fe88c4350fc7e
secret          :       4d7920736563726574
