Lua Requires Chilkat v11.5.0+

Create CAdES (p7m) Signature using ARSS (Aruba Remote Signing Service)

See more Signing in the Cloud Examples

Demonstrates creating a CAdES (p7m) signature using the Aruba Remote Signing Service. Lua

local chilkat = require("chilkat")

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

-- Load the certificate used for signing.  The certificate's private key is stored on
-- the Aruba.it server and the signing will happen remotely using the
-- ARSS (Aruba Remote Signing Service).
-- However, we still need the certificate locally (without private key).
local cert = chilkat.Cert.new()
local success = cert:load_from_file("qa_data/certs/myCert.cer")
if not success then
    print(cert.last_error_text)
    return
end

-- To sign using the Aruba Remote Signing Service,
-- add the following lines of code to specify your authentication credentials,
-- and the ID of the certificate w/ private key on the server to be used.
local jsonArss = chilkat.JsonObject.new()

-- Set the "service" equal to "ARSS" to tell Chilkat to use ARSS for signing.
jsonArss:update_string("service", "ARSS")
-- Specify the certificate ID, such as "AS0"
-- This certificate should match the certificate loaded in the above code.
jsonArss:update_string("certID", "YOUR_ARSS_CERT_ID")
jsonArss:update_string("otpPwd", "YOUR_OTP_PWD")

-- Specifies the OTP authentication environment.
--
-- Common values are:
--   "demoprod" - Demo/Test environment
--   "prod"     - Production environment
--
-- This value is sent to the ARSS service and determines how the OTP
-- authentication is validated.  The correct value depends on the type
-- of Aruba account and environment that has been provisioned.
--
-- If signing fails with an authentication-related error, verify that
-- the typeOtpAuth value matches the environment associated with the
-- ARSS account credentials being used.
jsonArss:update_string("typeOtpAuth", "demoprod")

jsonArss:update_string("user", "YOUR_ARSS_USERNAME")
jsonArss:update_string("userPWD", "YOUR_ARSS_PASSWORD")

-- The "endpoint" can be specified.
