For this lab, you will be assigned a Key Plain Cipher triple to use. The triple is written as three values in hexadecimal being the key (64 bits), plaintext (64 bits) and ciphertext (64 bits) values respectively; and should look something like the following:

 5B5A57676A56676E 675A69675E5A6B5A 974AFFBF86022D1F

Encrypt the plaintext using the key given in your triple, with tracing of the round values. Note how the bits in X (the left and right halves of the data) change from round to round. What is the value of your X at the start of round 5?
