### Question:
CertificateCoder2 { public static void configSSLSocketFactory(HttpsURLConnection conn, String password, String keyStorePath, String trustKeyStorePath) throws Exception { conn.setSSLSocketFactory(getSSLSocketFactory(password, keyStorePath, trustKeyStorePath)); }  static byte[] encryptByPrivateKey(byte[] data, String keyStorePath,
                                             String alias, String password); static byte[] decryptByPrivateKey(byte[] data, String keyStorePath,
                                             String alias, String password); static byte[] encryptByPublicKey(byte[] data, String certificatePath); static byte[] decryptByPublicKey(byte[] data, String certificatePath); static boolean verifyCertificate(String certificatePath); static boolean verifyCertificate(Date date, String certificatePath); static String sign(byte[] sign, String keyStorePath, String alias,
                              String password); static boolean verify(byte[] data, String sign,
                                 String certificatePath); static boolean verifyCertificate(Date date, String keyStorePath,
                                            String alias, String password); static boolean verifyCertificate(String keyStorePath, String alias,
                                            String password); static void configSSLSocketFactory(HttpsURLConnection conn,

@Test public void testHttps() throws Exception { URL url = new URL("https: HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setDoInput(true); conn.setDoOutput(true); CertificateCoder2.configSSLSocketFactory(conn, clientPassword, clientKeyStorePath, clientKeyStorePath); InputStream is = conn.getInputStream(); int length = conn.getContentLength(); DataInputStream dis = new DataInputStream(is); byte[] data = new byte[length]; dis.readFully(data); dis.close(); System.err.println(new String(data)); conn.disconnect(); }
