Is there a way to reverse the function md5?
Of course I mean that there's a password after md5, and I want to return it to the original string.
Is it possible, if so how?
No, it's not possible. If you go to http://www.php.net/manual/en/function.md5.php and read the user submitted notes, you'll see that you shouldn't be using md5 for encrypting purposes, and that the md5 output doesn't contain the contents of the original string.

hello,
diego is right - md5 produces a checksum
