Lua Requires Chilkat v10.1.2+

SSL Client Certificate

See more Socket/SSL/TLS Examples

Demonstrates how to connect to an SSL server using a client-side certificate, send a simple message, receive a simple response, and disconnect. Lua

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

-- locate the certificate we need, and use it for signing.
