Encrypt and Decrypt the text using Atbash Cipher
This program performs Encryption and Decryption of the given text using Atbash Cipher method. It is monoalphabetic substitution cipher method where it replaces 'A' with 'Z' , 'B' with 'Y' , 'C' with 'X', etc. Due to the symmetric nature of this Cipher, the Decryption process is exactly the same as Encryption process.
