/**
 * Support for configuring TLS/SSL connections.
 *
 * <h2>Introduction</h2>
 *
 * This class was introduced to centralise the work of TLS/SSL configuration. It is intended to be
 * backwards compatible with earlier code (as much as possible) and so is perhaps more complex than
 * would be necessary if starting from zero - the main source of confusion is the distinction
 * between direct and indirect creation of sockets and stores.
 *
 * <h2>Configuration</h2>
 *
 * The documentation in this class is intended more for programmers than end uses. If you are
 * configuring a connector the interfaces {@link org.mule.umo.security.TlsIndirectTrustStore},
 * {@link TlsDirectTrustStore}, {@link TlsDirectKeyStore} and {@link TlsIndirectKeyStore} should
 * provide guidance to individual properties. In addition you should check the documentation for the
 * specific protocol / connector used and may also need to read the discussion on direct and
 * indirect socket and store creation below (or, more simply, just use whichever key store interface
 * your connector implements!).
 *
 * <h2>Programming</h2>
 *
 * This class is intended to be used as a delegate as we typically want to add security to an
 * already existing connector (so we inherit from that connector, implement the appropriate
 * interfaces from {@link org.mule.umo.security.TlsIndirectTrustStore}, {@link TlsDirectTrustStore},
 * {@link TlsDirectKeyStore} and {@link TlsIndirectKeyStore}, and then forward calls to the
 * interfaces to an instance of this class).
 *
 * <p>For setting System properties (and reading them) use {@link TlsPropertiesMapper}. This can
 * take a "namespace" which can then be used by {@link TlsPropertiesSocketFactory} to construct an
 * appropriate socket factory. This approach (storing to proeprties and then retrieving that
 * information later in a socket factory) lets us pass TLS/SSL configuration into libraries that are
 * configured by specifying on the socket factory class.
 *
 * <h2>Direct and Indirect Socket and Store Creation</h2>
 *
 * For the SSL transport, which historically defined parameters for many different secure
 * transports, the configuration interfaces worked as follows:
 *
 * <dl>
 *   <dt>{@link TlsDirectTrustStore}
 *   <dd>Used to generate trust store directly and indirectly for all TLS/SSL conections via System
 *       properties
 *   <dt>{@link TlsDirectKeyStore}
 *   <dd>Used to generate key store directly
 *   <dt>{@link TlsIndirectKeyStore}
 *   <dd>Used to generate key store indirectly for all TLS/SSL conections via System properties
 * </dl>
 *
 * Historically, many other transports relied on the indirect configurations defined above. So they
 * implemented {@link org.mule.umo.security.TlsIndirectTrustStore} (a superclass of {@link
 * TlsDirectTrustStore}) and relied on {@link TlsIndirectKeyStore} from the SSL configuration. For
 * continuity these interfaces continue to be used, even though the configurations are now typically
 * (see individual connector/protocol documentation) specific to a protocol or connector. <em>Note -
 * these interfaces are new, but the original code had those methods, used as described. The new
 * interfaces only make things explicit.</em>
 *
 * <p><em>Note for programmers</em> One way to understand the above is to see that many protocols
 * are handled by libraries that are configured by providing either properties or a socket factory.
 * In both cases (the latter via {@link TlsPropertiesSocketFactory}) we continue to use properties
 * and the "indirect" interface. Note also that the mapping in {@link TlsPropertiesMapper} correctly
 * handles the asymmetry, so an initial call to {@link TlsConfiguration} uses the keystore defined
 * via {@link TlsDirectKeyStore}, but when a {@link TlsConfiguration} is retrieved from System
 * proerties using {@link TlsPropertiesMapper#readFromProperties(TlsConfiguration,
 * java.util.Properties)} the "indirect" properties are supplied as "direct" values, meaning that
 * the "indirect" socket factory can be retrieved from {@link #getKeyManagerFactory()}. It just
 * works.
