PHP offers the function uniqid(). This function guarantees a unique string.
As such, the values from uniqid() are fairly predictable, and should not be used in encryption (PHPs rand(), by the way, is considered fairly unpredictable).
Running uniqid(), prefixed with rand() trough md5() give more unpredictable values:
The other benefit of this, is that md5() assures hashes (strings) that are 32 characters/numbers long.
