WS-SECURITY SOAP PHP

I need a php class that create for me the ws-security authentication in php soap. The dealers authentication is achieved by means of Username Tokens signed. The dealer that wants to send a request to the System, must enter a Username Token SOAP header of the message , it must sign with its private signature key and must then enter the SOAP header produced signature and its digital signature certificate . The Username Token must be enhanced with the " Common Name " of the digital certificate used for signing.
