(1 point) A cryptography student has accidentally used the same keystream

(1 point) A cryptography student has accidentally used the same keystream to encrypt two different messages, M1 and M2. We know that the ciphertexts are C1 = 0x4caf2c89a01de196 and C2 = Oxd953db2e6d3c6d15. We also happen to know that Mi 0x3534224b6bf0272a. a) What is M2 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
