  • Certificate - points to instance of TElX509Certificate class (see noted below)


    This event is fired by TElClientIndySSLIOHandlerSocket when the negotiated protocol requires a client-side X509 certificate to be used during session. TElIdFTPIOHandlerSocket fires OnCertificateNeededEx event consequently, until the nil/NULL value is passed as Certificate parameter. This gives the ability to pass a certificate chain to server, not only a single certificate. This event should be handled the following way:

  • Pass the whole certificate chain, starting from end-entity certificate with a corresponding private key.
  • When the chain is over, pass nil/NULL as Certificate parameter.

OnCertificateNeededEx can accept the certificate which belongs to the certain chain. In this case the whole chain is sent and OnCertificateNeededEx is not fired further.
