我在 StackOverflow 上到处搜索,但这些问题似乎与我的不同,我在修复它时遇到了很多麻烦。
现在,我的程序应该只使用 SSL 套接字建立客户端-服务器连接,其中客户端只发送一条消息并关闭(稍后我将添加更多内容)
我收到消息部分的问题和 No Cipher Suites in Common 错误。下面我将发布我的服务器和客户端代码以及输出。我正在使用 Ubuntu 16.04 和 Netbeans 8.2
服务器代码:
public static void main(String[] args)
throws IOException, KeyStoreException, NoSuchAlgorithmException,
CertificateException, UnrecoverableKeyException, KeyManagementException {
FileInputStream keyFile = new FileInputStream(archivoKey);//Server.jks with Client.crt and .key as well as Server.crt and .key
char[] archivopwd = mypassword.toCharArray();
String password = mypassword;
System.setProperty("javax.net.ssl.trustStore", archivoKey);
System.setProperty("javax.net.ssl.trustStorePassword", password);
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(keyFile, archivopwd);
KeyManagerFactory keyManagerFactory =
KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, archivopwd);
KeyManager keyManagers[] = keyManagerFactory.getKeyManagers();
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(keyManagers, null, null);
SSLServerSocketFactory factory=(SSLServerSocketFactory)
SSLServerSocketFactory.getDefault();
SSLServerSocket ss = (SSLServerSocket) factory.createServerSocket(6000);
System.out.println("Esperando conexion...");
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
SSLSocket so =(SSLSocket) ss.accept();
so.startHandshake();
System.out.println("Conexion realizada");
BufferedReader in = new BufferedReader
(new InputStreamReader(so.getInputStream()));
String msg = in.readLine();
System.out.println(msg);
}
服务器输出:

客户端代码
public static void main(String[] args) {
int port = 6000;
String host = "localhost";
String password = mypassword;
System.setProperty("javax.net.ssl.trustStore", archivoKey);
System.setProperty("javax.net.ssl.trustStorePassword", password);
try {
SSLContext sc = SSLContext.getInstance("TLS");
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
InputStream keyFile = new FileInputStream(archivoKey); //Client.jks, exactly the same as the Server.jks
try {
keyStore.load(keyFile, archivopwd);
} finally {
if (keyFile != null) {
keyFile.close();
}
}
KeyManagerFactory keyManagerFactory =
KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, archivopwd);
sc.init(null, null, null);
SocketFactory factory = sc.getSocketFactory();
System.out.println("Buscando conexion...");
try (SSLSocket so = (SSLSocket) factory.createSocket(host, port)) {
so.getEnabledCipherSuites();
so.startHandshake();
System.out.println("Conexion exitosa!");
DataOutputStream os = new DataOutputStream(so.getOutputStream());
os.writeUTF("Prueba!");
}
} catch (Exception e) {
e.printStackTrace();
}
}
客户端输出

大多数东西(比如 System.setProperty 的东西)是我测试我在这里读到的几个选项。.jks 是通过将 crt 和密钥文件获取到 p12 文件并将它们添加到 .jks 来生成的。
我真的没有想法,所以任何帮助表示赞赏。您需要的其他任何内容都可以询问。谢谢
