Extracted text: Chapter 2: Problem 2 Previous Problem Problem List Next Problem A cryptography student has accidentally used the same keystream to encrypt two different messages, M1 and M2. We know that the ciphertexts are C1 Ox2374ab097b9d49df and C2 = 0xd99a87cfa7e29a51. We also happen to know that M1 = 0xa07eeaelc735bf3d. 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.
