    public interface KeyManager

This is the base interface for JSSE key managers.

`KeyManager`s are responsible for managing the key material which is used to authenticate the local SSLSocket to its peer. If no key material is available, the socket will be unable to present authentication credentials.

`KeyManager`s are created by either using a `KeyManagerFactory`, or by implementing one of the `KeyManager` subclasses.

Since:
  1.4
