(Xojo Plugin) SCP Download/Upload Binary Files as Encoded Strings

Demonstrates how to upload and download binary files as encoded strings (base64, hex, etc.) using the SCP protocol (Secure Copy Protocol over SSH).

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

Dim ssh As New Chilkat.Ssh

// Hostname may be an IP address or hostname:
Dim hostname As String
hostname = "www.some-ssh-server.com"
Dim port As Int32
port = 22

// Connect to an SSH server:
Dim success As Boolean
success = ssh.Connect(hostname,port)
If (success <> True) Then
    System.DebugLog(ssh.LastErrorText)
    Return
End If

// Wait a max of 5 seconds when reading responses..
ssh.IdleTimeoutMs = 5000

// Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
If (success <> True) Then
    System.DebugLog(ssh.LastErrorText)
    Return
End If

// Once the SSH object is connected and authenticated, we use it
// in our SCP object.
Dim scp As New Chilkat.Scp

success = scp.UseSsh(ssh)
If (success <> True) Then
    System.DebugLog(scp.LastErrorText)
    Return
End If

Dim remotePath As String
remotePath = "images/starfish.jpg"

// Download the binary file and return as a base64 string.
// See <a href="http://www.cknotes.com/chilkat-binary-encoding-list/">List of Encodings</a> for a list of possible encodings.
Dim encodedJpg As String
encodedJpg = scp.DownloadBinaryEncoded(remotePath,"base64")
If (scp.LastMethodSuccess <> True) Then
    System.DebugLog(scp.LastErrorText)
    Return
End If

remotePath = "images/starfish2.jpg"

// Now upload from the base64 string to the SSH server.
// Insided the call to UploadBinaryEncoded, the base64 string is decoded,
// and the decoded bytes are uploaded.  The resulting starfish2.jpg on the
// server will be identical to the original starfish.jpg
success = scp.UploadBinaryEncoded(remotePath,encodedJpg,"base64")
If (success <> True) Then
    System.DebugLog(scp.LastErrorText)
    Return
End If

System.DebugLog("SCP download/upload binary encoded success.")

// Disconnect
ssh.Disconnect
