I've been looking at the FTPS server sample and it seems that only password authentication is supported. Is it possible to support certificate authentication on any of your FTPS Servers (pref. with TELSimpleFTPSServer)?

If is it possible, can you give me a sample code of how to validate it ?

Hi. You should handle .OnEstablishSecureConnection event of TElFTPSServer instance, there you'll get access to SSLServer instance, and should configure it to request certificate, setup needed event handlers and so on.

To get to the TElFTPSServer instance, you should handle .OnNewConnection event of ElSimplFTPSServer - there you can get the ElSimpleFTPSServerSessionThread object, which has FTPSServer property.

I was looking for a SSLServer example to see how this works, but it needs the SSLSocket assembly that was not included in the package 11.0.239 for .Net 4

SSLSocket assembly is provided in source code. It's located in Classes folder.
