A particular cipher is implemented by using the XOR function. It can be even implemented with triple-XORed. In the process of encrypting a message, a character is XORed three times with the three different keys (pseudorandom bytes). If the three keys are 01101101, 10011100, and 11001010,
a. What is the ciphertext (in binary form) generated by the encryption of character B? (Please show your work.)
b. How is the plaintext if the ciphertext is 01111101? (Please show your work.)
