Hi,

What does following log mean? Does error “Failed to read incoming handshake messages” mean server respond problem?

The server is requesting a client-side certificate for authentication. It can be seen from this part of the LastErrorText:

        processTlsRecord:
          processHandshake:
            handshakeMessageType: CertificateRequest
            handshakeMessageLen: 0x11d

Your application, however, did not provide one. In this case, Chilkat will send a 0-length Certificates message, which is the only choice. See this part of the LastErrorText:

      Sending 0-length certificate (this is normal).
      CertificatesMessage:
        numCerts: 0
        CertificateSize: 0x3
      --CertificatesMessage

The solution is to provide an adequate client-side certificate via either the http.SetSslClientCert or http.SetSslClientCertPfx methods.

Here is my code, I do use the "http.SetSslClientCert', please let me know what's wrong in the code?

Thanks

Sam

    Memo1.Lines.Add('Response Status Code: '
         + IntToStr(responseStatusCode));

It may be that you also need an update for the ChilkatCert.dll Please download and use this one:

http://www.chilkatsoft.com/preRelease/ChilkatCert-9.5.0-win32.zip

Also, make sure to check the return value of the call to http.SetSslClientCert, to make sure that it did not fail..

I've updated the new "ChilkatCert.dll", just copied to "C:Program Files (x86)Chilkat Software IncChilkat HTTP ActiveX", is this operation correct?

Then I run application again, got following log. It said "The private key is not marked as exportable.". How can I make it exportable?

 cert := TChilkatCert.Create(Self);
  success := cert.LoadPfxFile(programpath+'TAMRCHQ.p12','4X019JT8');
  if (success <> 1) then
  begin
    Memo1.Lines.Add(cert.LastErrorText);
    Exit;
  end;
  success := http.SetSslClientCert(cert.ControlInterface As CHILKATHTTPLib_TLB.IChilkatCert);
  if (success <> 1) then
  begin
    Memo1.Lines.Add(http.LastErrorText);
    Exit;
  end;

this problem was solved finally. I used "http.SetSslClientCertPfx" instead of "http.SetSslClientCert".Then it works fine.
