WCF client - problem finding the right configuration

Question

Hi,
I'm trying to create a client for a Web Services which requires standard, WS-I SOAP 1.1 messages, through single sided https. SOAP must be signed with a user certificate, which is by the way not used for https, but is for end-to-end security. In SOAP there is a header and a body, and body only must be signed. I have the required certificates for the service.

When I try to set up my c# code, it either signs the message and uses http, or then if made for using https, then it signs and encrypts the message. Encryption is not allowed.

What would be the the right configuration to sign the body and use https?
Can I use basicHttpBinding at all, or how can it be configured for https? Or is wsHtppBinding the right one?
Where do I order the signature to be done for body only? Now the result is that each element in header is also signed.

BTW, SoapUI did the request from WSDL, and when adding the certificate, it did a valid message in no time. A copy of it is below. I should be able to create similar with WCF.
 
Thanks
