Need help with WS Security policy file for

an existing web service. The current process decrypts via .NET (WS Security encrytion) but we just upgraded to webMethods 7.1.2. I would like to get rid of the custom process to decrypt this data now that we have upgraded and webMethods has built in processes to handle WS Security. I will be the first to admit, the documentation confuses me a bit and I have read it a few times. I do think I need to implement a custom policy file but I can’t seem to get one to work. I can send to webMethods fine, receive the data but it isn’t decrypting. I have attached a sample of what the header looks like for this document. Does anyone have any ideas on how to build a corresponding policy file for this to decrypt? TIA, I have spent a lot of time on this but can’t seem to get it to work.
