(1 point) A cryptography student has accidentally used the same keystream to encrypt two different messages, M, and My. We know that the ciphertexts are C = Oxcbb8c821be2cc942 and C2 = 0x2128d7efbd388aa8. We also happen to know that M - Oxf878242306cf3478 a) What is M, in hexadecimal? Please give your answer a leading Ox and uso 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
