(JavaScript) Upload to Tumbleweed SecureTransport FTPS Server

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.

Note: This example requires Chilkat v10.1.2 or greater.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

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

// at 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.
