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

// Load the certificate used for signing.  The certificate's private key is stored on

// ARSS (Aruba Remote Signing Service).

// 
// 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.
