Consider the affine encryption cipher using A

please help solve the encryption problem , it is related to the encryption cipher

1.    Consider the affine encryption cipher using A=1, B=2, C=3, … given by C=3p+2(mod26). Give a decryption cipher(equation) and show that it works by first encrypting and then decrypting and letter T.

2.    Encrypt the word ”GO” using RSA with prime numbers p=13, q=17, and e=11.

a.    Use the extended Euclidean Algorithm to solve for the decryption exponent d.

b.    Use fast modular exponentiation to encrypt the letters “G” and O”

c.     Check that parts a and b are correct by decrypting the cyphertext.

3.    I sent the following word, encrypted with the public encryption key (47, 573, 571). Decrypt the message. (Hint: it is the best game ever)
