Note: This example requires Chilkat v11.0.0 or greater.

// See Global Unlock Sample for sample code.

// Most of the time a .jks contains one certificate with it's associated private key.
// (Similar to how a .pfx/.p12 usually contains a particular certificate with private key.)
// This example demonstrates how to get the certificate with private key such that it can be used
// by other Chilkat classes wherever a cert w/ private key is needed.
