Load P7B and List Certificates

Demonstrates how to load a .p7b containing certificates and accesses each individual certificate. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

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

    success = false;

    CkPem pem = new CkPem();

    //  Load the .p7b from a file.
