(Unicode C++) Load Java KeyStore and Access Contents

Loads a Java keystore file and iterates over the contents. A Java keystore (.jks) file can contain one or more trusted root certificate entries and/or one or more private key entries. Each private key entry includes an associated certificate chain.

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