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. Ruby

# 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.
jsonArss = Chilkat::CkJsonObject.new()

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