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. Go

    success := false

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

    ftp := chilkat.NewFtp2()

    // This code has been tested with the Tumbleweed server
    // at sft.wellsfargo.com
    ftp.SetHostname("sft.wellsfargo.com")

    // Use these exact strings for the username and password:
    ftp.SetUsername("site-auth")
    ftp.SetPassword("")

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

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

    // Load a certificate from a .pfx
    // A PFX may contain several certs, including the certificates
    // in a chain of authority.
    certStore := chilkat.NewCertStore()
    password := "***"
    // Load the certs from a PFX into an in-memory certificate store:
    success = certStore.LoadPfxFile("my.pfx",password)
    if success != true {
        fmt.Println(certStore.LastErrorText())
        ftp.DisposeFtp2()
        certStore.DisposeCertStore()
        return
    }

    // Find the desired certificate.
    jsonCN := chilkat.NewJsonObject()
    jsonCN.UpdateString("CN","cert common name")

    cert := chilkat.NewCert()

    // cert for the SSL connection:

    // Connect and authenticate with the FTP server.

    // Change to the remote directory where the file will be

    // account's home directory, this is not necessary.
