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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
$crypt = new COM("Chilkat.Crypt2");

// Duplicate the following results from RFC 4226

// Appendix D - HOTP Algorithm: Test Values
// 
//   The following test data uses the ASCII string
//   "12345678901234567890" for the secret:
//
