java - 带 SSL 的 RMI : Failed handshake

Question

我正在使用 RMI 编写一个客户端服务器应用程序，我想保护客户端和服务器之间的流量。为此，我想使用 SslRMIClientSocketFactory 和 SslRMIServerSocketFactory。

我已经为客户端和服务器创建了一个 key 对(client.private 和 server.private)，还为客户端和服务器创建了一个证书(client.public 和 server.public)。

我认为我正确地将 key 对添加到 keystore 并将证书添加到信任库。 我只在导出对象时使用自定义套接字工厂，而不是在创建 RMI 注册表时使用。这是我的代码:

服务器:

public class Server implements ServerProtocol {
    public Server() {
        super();
        SecureRandom sr = new SecureRandom();
        sr.nextInt();

        KeyStore clientKeyStore = KeyStore.getInstance("JKS");
        FileInputStream client = new FileInputStream("src/client.public");
        String passphrase = //
        clientKeyStore.load(client, passphrase.toCharArray());
        client.close();

        KeyStore serverKeyStore = KeyStore.getInstance("JKS");
        FileInputStream server = new FileInputStream("src/server.private");
        String password = //
        serverKeyStore.load(server, password.toCharArray());
        server.close();

        TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
        tmf.init(clientKeyStore);

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(serverKeyStore, password.toCharArray());

        SSLContext SSLC = SSLContext.getInstance("TLS");
        SSLC.init(kmf.getKeyManagers(), tmf.getTrustManagers(), sr);

        SslRMIClientSocketFactory csf = new SslRMIClientSocketFactory();
        SslRMIServerSocketFactory ssf = new SslRMIServerSocketFactory(null, null, true);

        LocateRegistry.createRegistry(2020).rebind("server", this);
        UnicastRemoteObject.exportObject(this, 2020, csf, ssf);
    }

    public void sayHello() {
        System.out.println("Hello");
    }
}

客户:

public class Client implements ClientProtocol {

    public Client() {
        SecureRandom sr = new SecureRandom();
        sr.nextInt();

        KeyStore serverKeyStore = KeyStore.getInstance("JKS");
        FileInputStream server = new FileInputStream("src/server.public");
        String passphrase = //
        serverKeyStore.load(server, passphrase.toCharArray());
        server.close();

        KeyStore clientKeyStore = KeyStore.getInstance("JKS");
        FileInputStream client = new FileInputStream("src/client.private");
        String password = //
        clientKeyStore.load(client, password.toCharArray());
        client.close();

        TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
        tmf.init(serverKeyStore);

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(clientKeyStore, password.toCharArray());

        SSLContext SSLC = SSLContext.getInstance("TLS");
        SSLC.init(kmf.getKeyManagers(), tmf.getTrustManagers(), sr);

        SslRMIClientSocketFactory csf = new SslRMIClientSocketFactory();
        SslRMIServerSocketFactory ssf = new SslRMIServerSocketFactory(null, null, true);

        Registry reg = LocateRegistry.getRegistry("localhost", 2020);
        serverStub = (ServerService) reg.lookup("server");
        stub = (ClientService) UnicastRemoteObject.exportObject(this, 2020, csf, ssf);

        serverStub.sayHello();
    }
}

当我运行它时，我收到以下错误消息:

我使用以下命令创建 key 、导出和导入它们:

keytool -genkey -alias clientprivate -keystore client.private -storetype JKS -keyalg rsa -storepass * -keypass * -validity 360
keytool -genkey -alias serverprivate -keystore server.private -storetype JKS -keyalg rsa -storepass * -keypass * -validity 360

keytool -export -alias clientprivate -keystore client.private -file temp.key -storepass *
keytool -import -noprompt -alias clientpublic -keystore client.public -file temp.key -storepass *

keytool -export -alias serverprivate -keystore server.private -file temp.key -storepass *
keytool -import -noprompt -alias serverpublic -keystore server.public -file temp.key -storepass *

我是否需要配置其他东西才能使其正常工作？ Eclipse 中有什么东西？

您正在使用 SSL 套接字工厂创建注册表，但没有向 getRegistry() 提供套接字工厂。
