1) Using any programming language of your choice implement the Rail Fence Cipher encryption algorithm 2) Specifications: The program should take two inputs

1) Message n

2) The key k, which is a tuple (d,r), where d is the depth of the cipher and r is the number of times the algorithm should repeat itself. The program should produce as output the encrypted message as text 3) What will be the decryption algorithm for a Rail-Fence cipher? Write down the pseudocode for the algorithm. 4) Using any programming language of your choice implement the Rail Fence Cipher decryption algorithm 5) Specifications: The program should take two inputs

1) Encrypted Message n

2) The key k, which is a tuple (d,r), where d is the depth of the cipher and r is the number of times the algorithm should repeat itself. The program should produce as output the decrypted message as text Test 1 (Encryption) 1) Using a key of (4,5) use your code to encrypt the following text: CRYPTOLOGY IS THE PRACTICE AND STUDY OF TECHNIQUES FOR SECURE COMMUNICATION IN THE PRESENCE OF THIRD PARTIES CALLED ADVERSARIES. 2) Do not ignore spaces Test 2 (Decryption) 1) Using a key of (3,3) use your code to decrypt the following text: TAOTINEN KAT I ODIOAEI OHHLSCTE TTETOEL BI IHI GAO EPSEA TO SS EEK ELRCPTSIY EANRPHMCYEK E CREAAIEJURTE IEASHI MA DRN RH AUWTA RF EFTFHENTPSF Q TAILB E TTECAPMSIYIY SRPURNTBL YCL OANAO E TVREAOSHOTTNULSRHK 2) Do not ignore spaces
