Go: Pointers at last

I’ve finally had to use pointers because I’m parsing command line flags

    blockPtr := flag.String("block", "YELLOW SUBMARINE", "the block to be padded")
    lengthPtr := flag.Int("length", 20, "final block length")

    n := *lengthPtr - len(*blockPtr)

Another thing I noted was that %02X formats a byte as a two character hexadecimal (padded with 0 in front)

    strs[i] = fmt.Sprintf("%02X",byte(n))

This won’t work for n > 255
