Demonstrates how to SFTP upload from a BinData object, and download into a BinData object. Lua

local chilkat = require("chilkat")

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

local sftp = chilkat.SFtp.new()

-- Set some timeouts, in milliseconds:
sftp.connect_timeout_ms = 5000
sftp.idle_timeout_ms = 10000

-- Connect to the SSH server and then authenticate.
