Encrypt MIME using a PEM certificate. Lua

local chilkat = require("chilkat")

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

local mime = chilkat.Mime.new()

-- Create a simple MIME message to be encrypted:
local success = mime:add_header_field("Content-Type", "text/plain")
success = mime:add_header_field("abc", "123")
mime:set_body("This is a test")

local cert = chilkat.Cert.new()
success = cert:load_from_file("qa_data/pem/mf_public_rsa.pem")
if not success then
    print(cert.last_error_text)
    return
end

-- Encrypt the MIME.
success = mime:encrypt(cert)
if not success then
    print(mime.last_error_text)
    return
end

-- Display the MIME:
print(mime:get_mime())

-- The resulting S/MIME looks like this:

-- Content-Type: application/x-pkcs7-mime; name="smime.p7m"; smime-type="enveloped-data"
-- abc: 123
-- Content-Disposition: attachment; filename="smime.p7m"
-- Content-Transfer-Encoding: base64
