Some background on "random numbers":

Java's Math.random(): float between 0 and 1
C++ rand(): integer between 0 and RAND_MAX (>= 32767)
Python's random.random(): float between 0 and 1
PHP's rand(): integer between 0 and (>=32768)

-> default minimum = 0

Key "number" is not descriptive! I'd favour keys integer & float.


Besides, t3lib_div::generateRandomBytes does not generate a string
usable for a "random password". It generates "byte"-sequences!

Generating a "random password" is a complex use case (character pools,
umlauts, character encodings). I'd focus on basics at first:
Integers, floats, hexstrings (see also t3lib_div::getRandomHexString()).


To comment Benjamin's comment in the bugtracker:
Having
stdWrap.hash = md5
is useless because you are not interested in a transformation (hashing
of an input) but only on the representation = a hex string
Thats why I mentioned hexstring instead of a hash key.
