Miguel -
MD5() is a "hash" function, not an encryption function. A hash function
cannot be reversed.
One of the reasons some sites use MD5() for passwords is so that the
passwords are never even stored on the server, only the hash. So even
the site's database admin can't figure out the passwords of users.
A hash is a little like a checksum. Two files can have the same
checksum even if they're completely different files. But good luck to
you if you want to CREATE a file with a specific checksum.

Is there a function opposite to md5()??
