帶有SSL的RMI：握手失敗

Question

我正在使用RMI編寫客戶端服務器應用程序，並且想要保護客戶端和服務器之間的通信安全。 我要為此使用SslRMIClientSocketFactory和SslRMIServerSocketFactory 。

我創建了一個密鑰對的客戶端和服務器（ client.private和server.private ），也為客戶端證書和服務器（ client.public和server.public ）。

我認為我正確地將密鑰對添加到密鑰庫，並將證書添加到信任庫。 我僅在導出對象時使用自定義套接字工廠，而不在創建RMI注冊表時使用。 這是我的代碼：

服務器：

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");
    }
}

客戶：

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();
    }
}

運行此命令時，出現以下錯誤消息：

我使用以下命令創建密鑰，導出和導入它們：

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東西才能使其正常工作？ Eclipse中有東西嗎？

Answer 1

您正在使用SSL套接字工廠創建注冊表，但沒有向getRegistry（）提供套接字工廠。

Answer 2

通過避免內置Java類SslRMIClientSocketFactory和SslRMIServerSocketFactory並創建自己的實現RMIClientSocketFactory和RMIServerSocketFactory接口的類，我能夠解決此問題。

的RMIClientSocketFactory

public class MyClientSocketFactory implements RMIClientSocketFactory, Serializable {

    public MyClientSocketFactory() {}

    public Socket createSocket(String host, int port) {

        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);

        SSLSocketFactory sf = SSLC.getSocketFactory();
        SSLSocket socket = (SSLSocket) sf.createSocket(host, port);

        return socket;
    }

    public int hashCode() {
        return getClass().hashCode();
    }

    public boolean equals(Object obj) {
        if (obj == this) {
            return true;
        } else if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        return true;
    }

}

的RMIServerSocketFactory

public class MyServerSocketFactory implements RMIClientSocketFactory, Serializable {

    public MyServerSocketFactory() {}

    public Socket createSocket(String host, int port) {

        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(serverKeyStore);

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

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

        SSLServerSocketFactory sf = SSLC.getServerSocketFactory();
        SSLServerSocket socket = (SSLServerSocket) sf.createServerSocket(host, port);

        return socket;
    }

    public int hashCode() {
        return getClass().hashCode();
    }

    public boolean equals(Object obj) {
        if (obj == this) {
            return true;
        } else if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        return true;
    }
