Obfuscate Your Company

md5(rand())) doesn't really make much sense. It's slightly less random than just using rand().

But it has a constant length and hides randomness from the observer.

"Hide randomness" ?

From hashes you'll recognize the fingerprint of the hash function but not the underlying data. Here is an example of random UIDs, generating a few user's in a row and it's obvious that it's random: random.sample(xrange(10000), 10) [88, 3833, 6353, 8113, 8983, 4280, 7878, 3050, 9409, 404]

So?

And if you generated random IDs with the same number of bits as a hash function they would be indistinguishable.

The code in the article comes from the example of this page http://www.php.net/manual/en/function.uniqid.php which has an interesting comments section on unique ids.
