2) Encode the letters 'A' to 'Z' as the numbers 10 to 35, respec- tively. Taking p = 47, q = 83, use the Rabin cryptosystem to encode the message consisting of the first two letters of your family name (in the unlikely event that your name only has on letter, add a second letter). Note that the two letters yield a single, 4-digit block for encryption, not two 2-digit blocks. Decrypt the encrypted message. As part of your solution present in full all computations, including both encoding and decoding.
