I'm using the Distributed Cryptography Add-on to sign XML files, but must include the information in the signature certificate used (X509Data). I need to display the information and the signature certificate used on a specific page.

thank you

Hello.

You can enable this using ((TElXMLKeyInfoX509Data)TElXMLSigner.KeyData).IncludeDataParams property. Please refer to the documentation for details: http://www.eldos.com/documentation/sb...arams.html

Thank you for the awnser.

I put this code on my PreSigner class:

Quote
((TElXMLKeyInfoX509Data) signer.KeyData).IncludeDataParams = SBXMLSec.Unit.xkidX509Certificate;


Correct?

But, in result.aspx page the property KeyData is null.

It must be assigned manually. Please refer to the next sample for details: \EldoS\SecureBlackbox.NET\Samples\C#\XMLBlackbox\Signer

You would need to create an instance of TElXMLKeyInfoX509Data, and then set a Certificate property with a signing certificate. To obtain a signing certificate from a state object, please do following:
Code
  TElDCBaseMessage Msg = State.FindMessageByType(TElDCOperationResponseMessage);
  if (Msg != null)
  {
    byte[] buf = TElDCOperationResponseMessage(Msg).KeysRDN.GetFirstValueByOID(      SBDCPKIConstants.Unit.SB_OID_DC_SIGNING_CERTIFICATE)
   // then load certificate from a buffer
  }


P.S. Please also ensure that TElXMLSigner.IncludeKey property is set to true for both steps.

Thanks, Dmytro and Vesevolod.

Works, with a little adjusts. I will put here the code for future references:

Code
byte[] buf = ((TElDCOperationResponseMessage)Msg).KeysRDN.GetFirstValueByOID(SBDCPKIConstants.Unit.SB_OID_DC_SIGNING_CERTIFICATE);
                var cert = new TElX509Certificate();
                cert.LoadFromBuffer(buf);
