I find rand_str($len , "1..9a..f\x4F") easier... ;-)
And this is still yielding exactly 16 differerent characters.

As you saw for yourself, it is not trivial to implement something like this
in userland. For example str_pad is way easier to implement, only some
playing with str_repeat.

Are there any objections if I implement this? Are you still against this new
