| ErrorCode | Required. A Long value. Code for certificate error, if any. |
| ErrorText | Required. A String value. Text description of the error, if any. |
| Accept | Required. A Boolean value. When set to False wodFtpDLX will close the connection. |
Remarks
This method is called only if you implemented IwodFtpNotify interface in your application, and wodFtpDLX.Notification property has received reference to instance of your implementation.
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.
