(Ruby) Create CAdES-BES .p7m using Smart Card or USB Token

Demonstrates how to create a CAdES BES invoice.xml.p7m using a certificate stored on a smart card or USB token.

Note: This example requires Chilkat v9.5.0.77 and at the time of this writing is restricted to the Windows operating system.

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

# Load the certificate on the smartcard currently in the reader (or on the USB token).
# Pass an empty string to allow Chilkat to automatically choose the CSP (Cryptographi Service Provider).
# See Load Certificate on Smartcard for information about explicitly selecting a particular CSP.
