FTPS / Implicit SSL

See more FTP Examples

Demonstrates how to connect using implicit SSL on port 990. The FTP component connects using SSL on port 990, which is the de-facto standard FTP SSL port. Not all FTP servers support implicit SSL. An alternative is to use AUTH SSL (also called AUTH TLS). .NET Core C#

bool success = false;

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Ftp2 ftp = new Chilkat.Ftp2();

// If this example does not work, try using passive mode
// by setting this to true.
ftp.Passive = false;
ftp.Hostname = "ftp.something.com";
ftp.Username = "test";
ftp.Password = "test";
ftp.Port = 990;

// We don't want AUTH SSL:
ftp.AuthTls = false;

// We want Implicit SSL:
ftp.Ssl = true;

// Connect and login to the FTP server.
success = ftp.Connect();
if (success != true) {
    Debug.WriteLine(ftp.LastErrorText);
    return;
}
else {
    // LastErrorText contains information even when
    // successful. This allows you to visually verify
    // that the secure connection actually occurred.
    Debug.WriteLine(ftp.LastErrorText);
}

Debug.WriteLine("FTPS Channel Established!");

// Do whatever you're doing to do ...
// upload files, download files, etc...

success = ftp.Disconnect();
