(Xojo Plugin) Secure FTP with Client Certificate

Chilkat FTP2 provides the ability to use a client certificate with secure FTP (implicit or explicit SSL/TLS). This example demonstrates how to load a certificate from a .pfx and use it as the client-side SSL cert. Note: Client-side certificates are only needed in situations where the server demands one.

Dim ftp As New Chilkat.Ftp2

Dim success As Boolean

//  Any string unlocks the component for the 1st 30-days.
success = ftp.UnlockComponent("Anything for 30-day trial")
If (success <> True) Then
    System.DebugLog(ftp.LastErrorText)
    Return
End If

ftp.Hostname = "ftp.***.com"
ftp.Port = 21
ftp.Username = "test"
ftp.Password = "test"

//  This example will use explict TLS/SSL.
//  Establish an explicit secure channel after connection
//  on the standard FTP port 21.
ftp.AuthTls = True

//  The Ssl property is for establishing an implicit SSL connection
//  on port 990.  Because this example uses explicit SSL, it
//  should remain False.
ftp.Ssl = False

//  Load a certificate from a .pfx
//  A PFX may contain several certs, including the certificates
//  in a chain of authority.
Dim certStore As New Chilkat.CertStore
Dim password As String
password = "***"
//  Load the certs from a PFX into an in-memory certificate store:
success = certStore.LoadPfxFile("chilkat.pfx",password)
If (success <> True) Then
    System.DebugLog(certStore.LastErrorText)
    Return
End If

//  Find the exact cert we'll use:
Dim cert As Chilkat.Cert
cert = certStore.FindCertBySubject("Chilkat Software, Inc.")
If (cert Is Nil ) Then
    System.DebugLog("Certificate not found!")
    Return
End If

//  Use this certificate for our secure (SSL/TLS) connection:
success = ftp.SetSslClientCert(cert)

//  Connect and login to the FTP server.  The connection is
//  made secure because of the AuthTls setting.
success = ftp.Connect()
If (success <> True) Then
    System.DebugLog(ftp.LastErrorText)
    Return
Else
    //  LastErrorText contains information even when
    //  successful. This allows you to visually verify
    //  that the secure connection actually occurred.
    System.DebugLog(ftp.LastErrorText)
End If

System.DebugLog("Secure FTP Channel Established!")

//  Do whatever you're doing to do ...
//  upload files, download files, etc...

//  .....
//  .....

success = ftp.Disconnect()
