(Visual FoxPro) 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.

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Ftp2')
loFtp = CreateObject('Chilkat.Ftp2')

* This code has been tested with the Tumbleweed server
* at sft.wellsfargo.com
loFtp.Hostname = "sft.wellsfargo.com"

* Use these exact strings for the username and password:
loFtp.Username = "site-auth"
loFtp.Password = ""

* Establish an AUTH SSL secure channel after connecting.
* Your client-side certificate is used for authentication when
* the SSL channel is established.
loFtp.AuthSsl = 1

* The Ssl property is for establishing an implicit SSL connection
* on port 990.  Do not set it.
loFtp.Ssl = 0

* Load a certificate from a .pfx
* A PFX may contain several certs, including the certificates
* in a chain of authority.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.CertStore')
loCertStore = CreateObject('Chilkat.CertStore')
lcPassword = "***"
* Load the certs from a PFX into an in-memory certificate store:
lnSuccess = loCertStore.LoadPfxFile("my.pfx",lcPassword)
IF (lnSuccess <> 1) THEN
    ? loCertStore.LastErrorText
    RELEASE loFtp
    RELEASE loCertStore
    CANCEL
ENDIF

* Find the exact cert we'll use:
loCert = loCertStore.FindCertBySubject("My Certificate 123 ABC")
IF (loCertStore.LastMethodSuccess = 0) THEN
    ? "Certificate not found!"
    RELEASE loFtp
    RELEASE loCertStore
    CANCEL
ENDIF

* Tell the Chilkat FTP2 component to use the client-side
* cert for the SSL connection:
lnSuccess = loFtp.SetSslClientCert(loCert)

* Connect and authenticate with the FTP server.
lnSuccess = loFtp.Connect()
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    RELEASE loCertStore
    CANCEL
ELSE
    * LastErrorText contains information even when
    * successful. This allows you to visually verify
    * that the secure connection actually occurred.
    ? loFtp.LastErrorText
ENDIF

? "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.
lnSuccess = loFtp.ChangeRemoteDir("someSubDir")
IF (lnSuccess <> 1) THEN
    ? loFtp.LastErrorText
    RELEASE loFtp
    RELEASE loCertStore
    CANCEL
ENDIF

* 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.
lcLocalFilename = "someFile.dat"
lcRemoteFilename = "someFile.dat"

* Upload the file.
lnSuccess = loFtp.PutFile(lcLocalFilename,lcRemoteFilename)
