(Visual FoxPro) 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.

Note: This example requires Chilkat v9.5.0.96 or later.

* 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).

* 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.
loJsonArss = CreateObject('Chilkat_9_5_0.JsonObject')

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