*  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.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")

*  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.
loJsonArss.UpdateString("typeOtpAuth","demoprod")

loJsonArss.UpdateString("user","YOUR_ARSS_USERNAME")
loJsonArss.UpdateString("userPWD","YOUR_ARSS_PASSWORD")

*  The "endpoint" can be specified starting in Chilkat v11.5.0
loJsonArss.UpdateString("endpoint","https://app1.firma-remota.it/ArubaSignerService/webresources/signerservice")
