I have several web services written in C# with WCF which has several hundreds of web methods in it. &nbsp;A new requirement came up that I have to implement SSL on IIS and also do encryption/decryption with message digest at the web service method level. &nbsp;My initial thought was to re-visit all the web methods and apply encr/decr to those specific sensitive fields but with time constraint, is not possible. &nbsp;Is there a way to apply encryption at the SOAP level, e.g. encrypting/decrypting the SOAP body? &nbsp;In this way, I could probably use the entire SOAP body to create the message digest. &nbsp;Please provide guidance, ideas or links to documentations. &nbsp;I tried searching but I could not find a good one. &nbsp;Thanks.

WCF C# web service encryption

Windows Communication Foundation (WCF) is a tool used to implement and deploy a service-oriented architecture (SOA) to support distributed computing where services have remote consumers. It features a runtime and a set of APIs in the .NET Framework for building connected, service-oriented applications. Services typically have a WSDL interface (Web Services Description Language) that any WCF client can use to consume the service, regardless of which platform the service is hosted on. WCF implements many advanced Web services (WS) standards such as WS-Addressing, WS-ReliableMessaging, WS-Security, RSS Syndication Services, WS-Discovery, routing and better support for REST services.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).
