Q1) A particular cipher is executed by combining ASCII representation of plaintext characters with pseudorandom bytes (eight-bit binary strings of 1s and 0s) using XOR function. In process of encrypting a message, character in the plaintext is XORed with the pseudorandom byte 10110101.
a. Determine ciphertext (in binary form) generated by encryption of character X?
b. What is the plaintext for the ciphertext 11110110?
