Use PuTTY Key for SSH Tunnel (PPK Private Key)

See more SSH Tunnel Examples

Demonstrates how to authenticate with a username + .ppk PuTTY private key w/ SSH Tunnel. Lua

local chilkat = require("chilkat")

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

local tunnel = chilkat.SshTunnel.new()

-- Load a .ppk PuTTY private key.
local puttyKey = chilkat.SshKey.new()
local ppkText = puttyKey:load_text("qa_data/ppk/putty_private_secret.ppk")

-- The ppkText contains this content:
