C Program to Implement Play fair Cipher Algorithm

Introduction

Encryption and decryption require a cipher. The ciphertext is the term used to describe it. Different algorithms may transform plain text to encoded text using the ciphertext process. The first practical digraph substitution cipher was the Play fair cipher. In this type of cipher, we encrypt a pair of alphabets instead of a single alphabet.
