(AutoIt) Sign Manifest File to Generate a Passbook .pkpass file

Demonstrates how to create a Passbook .pkpass archive by creating a signature of a manifest file and then zipping to a .pkpass archive.

Note: Chilkat also has the capability to do everything in-memory (no files would be involved). If this is of interest, please send email to support@chilkatsoft.com

Note: This example requires Chilkat v9.5.0.75.

; Note: Requires Chilkat v9.5.0.75 or greater.

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