HostCertificate event

Fires when remote server provides its certificate.


  • Basic
Private Sub object_HostCertificate(Cert, ErrorCode, ErrorText, Accept)
The HostCertificate(object,Cert,ErrorCode,ErrorText,Accept) syntax has these parts:
objectA wodFtpDLX object.
CertAn ICertificate object. Reference to Certificate object that holds information about server's certificate.
ErrorCodeA Long value. Code of the error, if any.
ErrorTextA String value. Text description of the error, if any.
AcceptA Boolean value. When set to False, wodFtpDLX will close the connection.


Once wodFtpDLX connects to SSL/TLS server, it will receive server's certificate that holds information about server's validity. It will contain information such as server's name, organization, valid dates etc.. Certificates are usually signed by some known CA (Certificate Authority) whose responsibility is to prove that server is really the one he's representing to be.

wodFtpDLX will try to detect if remote certificate should be trusted or not. If any errors are found, ErrorText will contain line-by-line descriptions for all errors found, and ErrorCode will contain first error that was found. If ErrorText is empty (and ErrorCode is 0), certificate should be trusted. wodFtpDLX will load all certificates in your Windows Certificate store (ROOT and MY stores) and remote certificate will be tested against all certificates in those stores.

Even if no error is found - make sure certificate's CommonName property point to the Hostname you're connecting to! This test should be done by your application.

If you think remote server's certificate is invalid, you should set Accept parameter to False and wodFtpDLX will immediately close the connection.
