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. Objective-C

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

//  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.

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