(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=0x2374ab097b9d49df and C2=0xd99a87cfa7e29a51. We also happen to know that M1=0xa07eeae1c735bf3d.

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.
