How to implement WSS: X509 Token Profile 1.0 on a WCF Web Service (Server Side)

I'm newer at creating WCF web services and I'm trying to figure out how to create a WCF service that conforms to the WSS:X509 Token Profile 1.0. There are many posts about how to do the client configuration however, not much about server configurations.
This project began as a WSDL-first generated service, so I am unable to change anything about how the client sends data to me, and I'm required to make the service conform to the data they send.
I've gone and created a custom endpoint for this service, however this is where i'm stuck. I'm sure theres just some small detail i'm missing to make it conform to the pdf below:
