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, navguru
