WCF JSON service with request content encrypted - json

Question

a Json WCF service method looks like this:
getFoo(MyDataType data){ ...
WCF automaticly translates the HTTP request that looks like:
randomGuy{
name:'John',
age:18
}
into the C# defined type
MyDataType{
string name {get;set;}
int age {get;set;}
}
But if I encrypt the request content, instead of receiving a request that looks like
randomGuy{
name:'John',
age:18
}
I will receive
wceweuicn23cb38v934vb398v03c264vb834gv3v7b3vb3647v34vb3v83vh38v43vhv3hv
Is there any way to first decrypt the request content into randomGuy{
name:'John',
age:18
} before WCF translates the JSON object into the .net defined type MyDataType?

Answer 1

To me, you have about 2 options:
Option 1: Use SSL for the connection so the message is protected.
Option 2: Intercept the message
In summary, I believe that the answer you are looking for are along the lines of an IClientMessageInspector which will allow you to manipulate messages and intercept them if neccessary on you WCF client. This article should explain it somewhat - enter link description here

Answer 2

Looks like the IDispatchMessageInspector or IDispatchMessageFormatter may help you in this case. And in general check the System.ServiceModel.Dispatcher namespace - there are other helpful staff.
The idea with IDispatchMessageInspector, that you are able to change (decrypt in your case) the incoming message before it's converted to a .NET object from JSON one.
