Question: (1 point) A cryptography student has accidentally used the same keystream to encrypt two different messages, M, and M . We know that the ciphertexts

(1 point) A cryptography student has accidentally used the same keystream to encrypt two different messages, M, and M . We know that the ciphertexts are C = Oxa536005a9b888e9e and C2 = 0.77616e6f856c8229. We also happen to know that M = 0x9d0ee2c58a7a83fc. a) What is M, in hexadecimal? Please give your answer a leading Ox and use lowercase letters only. b) What is the keystream? Please give your answer a leading Ox and use lowercase letters only. Hint: These are all 8 byte numbers and will fit in an unsigned long type on most systems
