public class ApplicationKeyManagerUtils
extends java.lang.Object

ApplicationKeyManagerUtils provides public methods for utilizing the application PKI key management, including access to trusted issuers (i.e., CA certificates), token signing and validation, and the ability to generate keystores for testing or when a self-signed certificate will suffice.
