I have developed a web service and the relevant wsdl file and am now looking at the various ways to add digital signatures to the web service. Using public/private certificates, keys seems the best way and have also looked at the soap dig-sig methods. What I can't seem to find an answer to is whether I need to specify any of this in my wsdl file so would really appreciate any advice on whether this needs to be done or if I just control the encryption from the function the web service calls? Thanks
