We have the following encryption algorithm: XOR with the hex key AB, rotate 5 places to the left, and XOR with the hex key C4.
Â
a. If we start with the bit pattern represented by the hex number 1234, what would the hex number be that represents the encrypted bit pattern?
Â
b. Assume that we have intercepted a message that was encoded using the same algorithm. The encoded message as a hex number was FADE. What was the original message as a hex number?
