Demonstrates how to implement keyboard authentication with an SSH server. AutoIt

; The standard SSH port = 22
; The hostname may be a hostname or IP address.

; See the online reference documentation for Chilkat SSH.
; The XML returned by StartKeyboardAuth will contain an infoRequest
; with one or more prompts that your application may choose to display.

; Call ContinueKeyboardAuth, passing in the whatever information is requires (such as the password).
; Typically, keyboard authentication requires one call to ContinueKeyboardAuth 
; using the password.  Theoretically, the SSH server could prompt for additional pieces
; of information.  The authentication is completed when the XML returned contains
; either a "success" or "error" child node.

; This example asumes only one call to ContinueKeyboardAuth is required.
