(AutoIt) SSH Tunnel Set Allowed AlgorithmsSee more SSH Tunnel ExamplesDemonstrates how to explicitly set the algorithms allowed in the SSH connection protocol for SSH tunneling. Note: This example requires Chilkat v9.5.0.99 or greater.
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code.
