	Comes from a SO comment

	@Josh K: This is a little over-the-top: $hash = sha1(sha1($password) ^ $salt);, $hash = sha1($password.$salt); would work just as well in practice (and faster). Also, the only reason I can think of to sha1(microtime()) is to constrain it to something that can fit in your column, and substr(str(microtime()), 0, 160) would work equally well (and faster), although I doubt microtime() gives a > 160 digit number anyway. Of course, you might be intentionally making it slow (so it would take more time to crack), but the performance should at least be mentioned.
