(AutoIt) Sign PDF using ARSS (Aruba Remote Signing Service)

See more Signing in the Cloud Examples

Demonstrates how to sign a PDF using the Aruba Remote Signing Service (ARSS).

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

; This example requires the Chilkat API to have been previously unlocked.
; See Global Unlock Sample for sample code.
