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

See more Digital Signatures Examples

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.
