(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 = 0x439d0f2ea13ec399 and C₂ = 0x0f2519014163dfdc. We also happen to know that M₁ = 0x1ae3d26121ed8cae. a) What is M₂ in hexadecimal? Please give your answer a leading Ox and use lowercase letters only. 0x564bc44ec1b090eb b) What is the keystream? Please give your answer a leading Ox and use lowercase letters only. 0x596edd4f80d34f37 Hint: These are all 8 byte numbers and will fit in an unsigned long type on most systems.
