Cryptography is the science and art of codes that makes it possible for two people to exchange data in such a way that other people cannot understand the message. In this paper, the authors are concerned with methods of altering data such that its recipient can undo the alteration and discover the original text. The original text is called PlainText (PT) while altered text is CipherText (CT). Conversion from PT to CT is called encoding/enciphering as codes that result from this process are called ciphers. The reverse operation is called decoding/deciphering.
