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. Swift

func chilkatTest() {
    var success: Bool = false

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

    let ftp = CkoFtp2()!

    // 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.
    let certStore = CkoCertStore()!
    var password: String? = "***"
    // Load the certs from a PFX into an in-memory certificate store:
    success = certStore.loadPfxFile(path: "my.pfx", password: password)
    if success != true {
        print("\(certStore.lastErrorText!)")
        return
    }

    // Find the desired certificate.
    let jsonCN = CkoJsonObject()!
    jsonCN.updateString(jsonPath: "CN", value: "cert common name")

    let cert = CkoCert()!
    success = certStore.findCert(json: jsonCN, cert: cert)
    if success == false {
        print("Certificate not found!")
        return
    }

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

    // Connect and authenticate with the FTP server.
    success = ftp.connect()
    if success != true {
        print("\(ftp.lastErrorText!)")
        return
    }
    else {
        // LastErrorText contains information even when
        // successful. This allows you to visually verify
        // that the secure connection actually occurred.
        print("\(ftp.lastErrorText!)")
    }

    print("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.
    success = ftp.changeRemoteDir(relativeDirPath: "someSubDir")
    if success != true {
        print("\(ftp.lastErrorText!)")
        return
    }

    // You may include an absolute or relative path with the 
    // local filename.  If no path is included, the file should 
    // be present in the current working directory of the calling
    // process.
    var localFilename: String? = "someFile.dat"
    var remoteFilename: String? = "someFile.dat"

    // Upload the file.
