+When padding is used, the number of bytes of padding is encoded in the following bytes. Values 
+from 0-254 indicate that 0-254 bytes of padding are included at the end. If the value is 255,
+then the padding is 254 bytes, plus the padding value encoded in the next byte. By using code
+255 multiple times, it is possible to add any amount of padding. The padding bytes produced by
