The Standard Algorithm Name of KeyManagerFactory
In JDK 7, "PKIX" was defined as the standard algorithm name of KeyManagerFactory.
It's a factory for X509ExtendedKeyManagers that manages X.509 certificate-based key pairs for local side authentication according to the rules defined by the IETF PKIX working group in RFC 3280 or its successor. The KeyManagerFactory must support initialization using the class javax.net.ssl.KeyStoreBuilderParameters.
