Use Installed Cert on Windows for TLS Client Authentication

See more HTTP Examples

Demonstrates how to use a certificate that has already been installed on a Windows PC for TLS client authentication. Lua

local chilkat = require("chilkat")

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

local http = chilkat.Http.new()

-- On Windows, a pre-installed certificate can be loaded in a number of different ways.
-- This example loads by the common name:
local cert = chilkat.Cert.new()
local success = cert:load_by_common_name("My ECA Medium Assurance Identity Certificate")
if not success then
    print(cert.last_error_text)
    return
end

-- Make sure this certificate has a private key available.
-- It should be a private key such that when the certificate was installed, it was marked as "exportable"
-- so that authorized programs are able to access the private key.
if not cert:has_private_key() then
    print("A private key is needed for TLS client authentication.")
    print("This certificate has no private key.")
    return
end

-- Set the certificate to be used for mutual TLS authentication
-- (i.e. sets the client-side certificate for two-way TLS authentication)
success = http:set_ssl_client_cert(cert)
if not success then
    print(http.last_error_text)
    return
end

-- At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
-- connection will automatically use it if the server demands a client-side cert.
