(1 point) A cryptography student has accidentally used the same keystream to encrypt two different messages, M and M2. We know that the ciphertexts are C 0x06c6d00e4633400a and C2 = 0xa01aa9692cf00a3e. We also happen to know that M = 0xa53ce953e84021f9. = 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.
