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()

-- Check the revocation status of the SSL server certificate for chilkatsoft.com
local status = http:ocsp_check("chilkatsoft.com", 443)

print("chilkatsoft.com status = " .. status)

-- The status can have 4 values:
-- -1: Unable to check because of an error.
--  0: Good
--  1: Revoked
--  2: Unknown

if status < 0 then
    print(http.last_error_text)

status = http:ocsp_check("revoked.badssl.com", 443)

print("revoked.badssl.com status = " .. status)
