Browser, I very much prefer your method of unpacking the MAC. I have implemented it into my code. Thank you for taking the time to explain. Now I am doubting everything I learned in class :/. I have an additional question, can I compare a packed MAC just as I can compare it after unpacked? like:

if($packed1 eq $packed2){
  print "The packed MACs match\n";
else{
  print "The packed MACs do not match\n";
}
