> If the input given is less than 16 bytes, we pad zero for the remaining bytes 
> [1]. This is not correct if the value is a negative number. We should pad 
> 0x00 or 0xFF depending upon the number is a positive or negative number. 
> Later when the value is retrieved we end up with an incorrect value.
