@ivoras - actually, and as a curiosity, that's essentially correct (it's an artifact of
the way ASCII is organized and of the way PHP handles bitwise operators on strings) - note that 0x18
& 0x32 = 0x10. The ASCII digit 'X' (for 0 to 9) is 0x3X, so ANDing two ASCII digits
will yield the correct hex digit.
