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

#  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).

#  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.

#  Set the "service" equal to "ARSS" to tell Chilkat to use ARSS for signing.

#  This certificate should match the certificate loaded in the above code.

#  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.
