How To Implement Monoalphabetic Cipher using C
Monoalphabetic Cipher is a method to encrypt messages by substituting one character for another character. This is fairly a simple method for encrypting data. Alike Ceaser Cipher, which have only 26 possible keys, Monoalphabetic Cipher has 26! possible keys (or possible ways to encrypt messages). In this tutorial, I will use the key pair given on Wikipediaas an example to illustrate the working of this cipher. Also I will encrypt the same…
How to implement Caesar Cipher using C
Caesar Cipher is the most basic cipher technique used to encrypt or decrupt messages. In this technique every character is replaced with the character standing particular number of places down the alphabet. That number serves the purpose of Key. So, for this Cipher technique, Key can only be a number ranging from 1 to 26. The most basic Caesar technique is Julius Cipher, in which Key is taken as 3….
