(VB.NET UWP/WinRT) 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 = "www.some-ssh-server.com"
Dim port As Integer = 22

' Connect to an SSH server:
Dim success As Boolean = Await ssh.ConnectAsync(hostname,port)
If (success <> True) Then
    Debug.WriteLine(ssh.LastErrorText)
    Exit Sub
End If


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

' Authenticate using login/password:
success = Await ssh.AuthenticatePwAsync("myLogin","myPassword")
If (success <> True) Then
    Debug.WriteLine(ssh.LastErrorText)
    Exit Sub
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
    Debug.WriteLine(scp.LastErrorText)
    Exit Sub
End If


Dim remotePath As String = "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 = Await scp.DownloadBinaryEncodedAsync(remotePath,"base64")
If (scp.LastMethodSuccess <> True) Then
    Debug.WriteLine(scp.LastErrorText)
    Exit Sub
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 = Await scp.UploadBinaryEncodedAsync(remotePath,encodedJpg,"base64")
If (success <> True) Then
    Debug.WriteLine(scp.LastErrorText)
    Exit Sub
