SCP Download/Upload Binary Files as Encoded Strings

See more SCP Examples

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

bool success = false;

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

Chilkat.Ssh ssh = new Chilkat.Ssh();

// Hostname may be an IP address or hostname:
string hostname = "www.some-ssh-server.com";
int port = 22;

// Connect to an SSH server:
success = ssh.Connect(hostname,port);
if (success != true) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

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

// Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword");
if (success != true) {
    Debug.WriteLine(ssh.LastErrorText);
    return;
}

// Once the SSH object is connected and authenticated, we use it
// in our SCP object.

// 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
