/**
 * Key or trust store options configuring private key and/or certificates based on Java Keystore files.
 * <p>
 * When used as a key store, it should point to a store containing a private key and its certificate.
 * When used as a trust store, it should point to a store containing a list of trusted certificates.
 * <p>
 * The store can either be loaded by Vert.x from the filesystem:
 * <p>
 * <pre>
 * HttpServerOptions options = HttpServerOptions.httpServerOptions();
 * options.setKeyStore(new JKSOptions().setPath("/mykeystore.jks").setPassword("foo"));
 * </pre>
 *
 * Or directly provided as a buffer:
 * <p>
 *
 * <pre>
 * Buffer store = vertx.fileSystem().readFileSync("/mykeystore.jks");
 * options.setKeyStore(new JKSOptions().setValue(store).setPassword("foo"));
 * </pre>
