****************************************************

You cannot convert it back, md5 is used to hash things, typically it is used for passwords, for example:

When a user registers an account the password is hashed with md5 and submited to a database:

$password = md5($_POST['password']);

The database will contain the password, but it will look like this:



Then when they login you md5 the submited password and compare that with the one in the databse, so the user is the only person who ever knows what the password actually is.
