It should also be pointed out that PHP contains no functions for decrypting a hashed string.
If you want to use md5() to encrypt users' passwords in a database, you would go about coding
the login by encrypting the submitted password
ie.
$user_submitted_password = md5($user_submitted_password);
$result = mysql_query("SELECT * FROM users WHERE
encrypted_password='$user_submitted_password'");
if (mysql_num_rows($result) < 1) { echo "Invalid password"; exit; }
else { echo "Correct password!"; }
