(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=0x5fa8bdfa8bcff672 and C2=0x7742bfe30a58e75c. We also happen to know that M1=0x527fc2599fe7a468. a) What is M2 in hexadecimal? Please give your answer a leading 0x and use lowercase letters only. b) What is the keystream? Please give your answer a leading 0x and use lowercase letters only. Hint: These are all 8 byte numbers and will fit in an unsigned long type on most systems
