Tutorial SOAP Security Header with C#

Hi Community,

I'm trying to add a security header to a soap-message via C# like SOAPUI it does.

Is there a tutorial describing this?

Her is the setup I'm using for request by soapui.

I've found a topic https://community.smartbear.com/t5/SoapUI-Open-Source-Questions/How-does-SOAPUI-calculate-the-SignatureValue-for-a-SignedInfo/td-p/174176 where a similar problem is mentioned.

I've copied code from this thread.

I also have different hash values for BinarySecurityToken generated once by soapui and another generated by C#.

BinarySecurityToken is a constant value that I could insert hard coded.

But the signature value depends on the definition of the body and will change every request.

Many thanks for your help.

Kind regard,
