You cannot 'decode' an md5() encrypted string.

Yes there are ways to encode and decode a string,
but that is not secure.
If you can decode the string, then so can everybody else.

Are you trying to encrypt the password and then test a user input string to see if it matches the encrypted password?

If so, you can md5() the user string and then compare the encrypted user string with the encrypted password.

If the md5() strings are the same string, then the password and the user string are the same.

Hope this helps.
