Upload to Tumbleweed SecureTransport FTPS Server

See more FTP Examples

Demonstrates how to connect, authenticate, and upload file to a Tumbleweed Secure Transport SSL FTP Server. Instead of providing a login name and password, you pass the string "site-auth" for the username, and an empty string for the password. You must also provide a client-side digital certificate -- as the certificate's credentials and validity are used to authenticate. 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();

//  This code has been tested with the Tumbleweed server
//  at sft.wellsfargo.com
ftp.Hostname = "sft.wellsfargo.com";

//  Use these exact strings for the username and password:
ftp.Username = "site-auth";
ftp.Password = "";

//  Establish an AUTH SSL secure channel after connecting.
//  Your client-side certificate is used for authentication when
//  the SSL channel is established.
ftp.AuthSsl = true;

//  The Ssl property is for establishing an implicit SSL connection
//  on port 990.  Do not set it.
ftp.Ssl = false;

//  Load a certificate from a .pfx
//  A PFX may contain several certs, including the certificates
//  in a chain of authority.
Chilkat.CertStore certStore = new Chilkat.CertStore();
string password = "***";
//  Load the certs from a PFX into an in-memory certificate store:
success = certStore.LoadPfxFile("my.pfx",password);
if (success != true) {
    Debug.WriteLine(certStore.LastErrorText);
    return;
}

//  Find the desired certificate.
Chilkat.JsonObject jsonCN = new Chilkat.JsonObject();
jsonCN.UpdateString("CN","cert common name");

Chilkat.Cert cert = new Chilkat.Cert();
success = certStore.FindCert(jsonCN,cert);
if (success == false) {
    Debug.WriteLine("Certificate not found!");
    return;
}

//  Tell the Chilkat FTP2 component to use the client-side
//  cert for the SSL connection:
success = ftp.SetSslClientCert(cert);

//  Connect and authenticate with 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("Secure FTP Channel Established!");

//  Change to the remote directory where the file will be
//  uploaded.  If your file is to be uploaded to the FTP user 
//  account's home directory, this is not necessary.
