Now let’s look at a more modern symmetric encryption. Assumethat the algorithm for thissystem is to rotate the bits in the message right 4 positions, XORthe bits with the key, and rotate the bits2 positions to the left.
KEY - C3
Using the key and the above algorithm, decrypt the followingmessage which contains a name(given in hex): 9D 5B 9C DC 87 1C 5F 5C. Remember that you willhave to reverse the order anddirection of operations in order to decrypt the name (i.e. Start byrotating 2 positions right). Whatis the name as it appears exactly in the message (use theunderscore _ to denote any blankspaces in your answer)?
