Question

Let's encrypt a message using RSA:
Choose p = 7 and q = 11, and then select e=13.
a.Compute d
b.Select plaintext message x=7. Produce the ciphertext y using the fast exponentiation
algorithm.
c. Decrypt the ciphertext (y) to verify that the initial plaintext (x) is produced. Again, please
use the fast exponentiation algorithm.
