Java：通过资源加载 SSL 密钥库

Question

如果我有：

System.setProperty("javax.net.ssl.keyStore", '/etc/certificates/fdms/WS1001237590._.1.ks');
System.setProperty("javax.net.ssl.keyStorePassword", 'DV8u4xRVDq');
System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", "true");

我能够毫无问题地打开安全连接。

但是，我希望将证书直接存储在战争中，因此我使用：（文件输入流最终将成为资源流，但我这样做是为了让它工作。）

System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", "true");
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream("/etc/certificates/fdms/WS1001237590._.1.ks"), "DV8u4xRVDq".toCharArray());
KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, "DV8u4xRVDq".toCharArray());
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(kmf.getKeyManagers(), null, null);

现在，如果我打开相同的连接，我得到：javax.net.ssl.SSLHandshakeException：收到致命警报：handshake_failure

不久前我不得不做类似的事情。我有一个证书文件，我必须找到一种方法来加载它并将其用于 SSL 连接。希望我所做的能够帮助你。

首先我必须创建一个信任管理器：

public class MyX509TrustManager implements X509TrustManager {

    X509TrustManager pkixTrustManager;

    MyX509TrustManager() throws Exception {

        String certFile = "/certificates/MyCertFile.cer";

        Certificate myCert = CertificateFactory.getInstance("X509").generateCertificate(this.getClass().getResourceAsStream(valicertFile));

        KeyStore keyStore = KeyStore.getInstance("JKS");
        keyStore.load(null, "".toCharArray());
        keyStore.setCertificateEntry("myCert", myCert);

        TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("PKIX");
        trustManagerFactory.init(keyStore);

        TrustManager trustManagers[] = trustManagerFactory.getTrustManagers();

        for(TrustManager trustManager : trustManagers) {
            if(trustManager instanceof X509TrustManager) {
                pkixTrustManager = (X509TrustManager) trustManager;
                return;
            }
        }

        throw new Exception("Couldn't initialize");
    }

    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        pkixTrustManager.checkServerTrusted(chain, authType);
    }

    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        pkixTrustManager.checkServerTrusted(chain, authType);
    }

    public X509Certificate[] getAcceptedIssuers() {
        return pkixTrustManager.getAcceptedIssuers();
    }
}

之后我必须创建一个使用我的信任管理器的套接字工厂：

public class MySSLProtocolSocketFactory implements SecureProtocolSocketFactory {

    private SSLContext sslContext = null;

    public MySSLProtocolSocketFactory() {
        super();
    }

    private static SSLContext createMySSLContext() {
        try {
            MyX509TrustManager myX509TrustManager = new MyX509TrustManager();
            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, new MyX509TrustManager[] { myX509TrustManager}, null);
            return context;
        }

        catch(Exception e) {
            Log.error(Log.Context.Net, e);
            return null;
        }
    }

    private SSLContext getSSLContext() {
        if(this.sslContext == null) {
            this.sslContext = createMySSLContext();
        }

        return this.sslContext;
    }

    public Socket createSocket(String host, int port, InetAddress clientHost, int clientPort) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(host, port, clientHost, clientPort);
    }

    public Socket createSocket(final String host, final int port, final InetAddress localAddress, final int localPort, final HttpConnectionParams params) throws IOException {
        if(params == null) {
            throw new IllegalArgumentException("Parameters may not be null");
        }

        int timeout = params.getConnectionTimeout();
        SocketFactory socketFactory = getSSLContext().getSocketFactory();

        if(timeout == 0) {
            return socketFactory.createSocket(host, port, localAddress, localPort);
        }

        else {
            Socket socket = socketFactory.createSocket();
            SocketAddress localAddr = new InetSocketAddress(localAddress, localPort);
            SocketAddress remoteAddr = new InetSocketAddress(host, port);
            socket.bind(localAddr);
            socket.connect(remoteAddr, timeout);
            return socket;
        }
    }

    public Socket createSocket(String host, int port) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(host, port);
    }

    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException {
        return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    public boolean equals(Object obj) {
        return ((obj != null) && obj.getClass().equals(MySSLProtocolSocketFactory.class));
    }

    public int hashCode() {
        return MySSLProtocolSocketFactory.class.hashCode();
    }
}

然后我使用该套接字工厂发送我的帖子：

Protocol.registerProtocol("myhttps", new Protocol("myhttps", new MySSLProtocolSocketFactory(), 443));

PostMethod postMethod = new PostMethod("myhttps://some.url.here");

HttpClient client = new HttpClient();
int status = client.executeMethod(postMethod);

我唯一不明白的是如何简单地添加证书文件到常规密钥库。我在研究过程中发现的所有示例源代码都指向创建一个套接字因子，然后向该套接字工厂注册一个协议。也许有一种方法可以简单地使用套接字工厂来建立连接，而无需注册协议；我还没有调查得很彻底。在我的特殊情况下，创建一个特定的协议是必要的。希望这能让您走得更远。我承认这似乎有点迂回；当我最初这样做时，我也有同样的感觉。但这是我让它发挥作用的唯一方法。也许其他人有更好的解决方案。

为了后代的缘故，所有这些都太复杂了，我们几乎只是在静态块中进行了检查：

if( environment == 'production') {
    System.setProperty("javax.net.ssl.keyStore",                    '/etc/certificates/prod/keystore.ks');
    System.setProperty("javax.net.ssl.keyStorePassword",            'password');
    System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", "true");
} else {
    System.setProperty("javax.net.ssl.keyStore",                    '/etc/certificates/test/keystore.ks');
    System.setProperty("javax.net.ssl.keyStorePassword",            'password');
    System.setProperty("sun.security.ssl.allowUnsafeRenegotiation", "true");
}

Answer 3

对于Axis，我认为您需要通过以下方式配置其SSLSocketFactory：

AxisProperties.setProperty("axis.socketSecureFactory",
    "com.example.MySSLSocketFactory");

其中com.example.MySSLSocketFactory是实现org.apache.axis.components.net的类.SecureSocketFactory（也许您可以扩展org.apache.axis.components.net.JSSESocketFactory）。

在 create 方法中，使用从您配置的 SSLContext 获取的套接字工厂创建套接字。

Answer 4

如果您愿意，这里有一个可以轻松创建 SSLSocket 和 SSLServerSocket 的 API：

https://github.com/gpotter2/SSLKeystoreFactories

它不需要任何其他罐子....只需获取文件并使用它们，例如：

SSLSocket s = SSLSocketKeystoreFactory.getSocketWithCert(ip, port, 
   Main.class.getResourceAsStream("/mykey.jks"), "password")

或者：

SSLServerSocket s = SSLServerSocketKeystoreFactory.getSocketWithCert(port, 
   Main.class.getResourceAsStream("/mykey.jks"), "password")

这更容易使用:)

Answer 5

我遇到了类似的问题，我解决了创建一个使用来自输入流的密钥库返回 SSL 上下文的函数。

   protected SSLContext getSslCtx(InputStream is, String password) {
    try {
        // Load keystore
        KeyStore keystore = KeyStore.getInstance("JKS");
        keystore.load(is, password.toCharArray());

        // Load trust manager
        TrustManagerFactory trustMgrFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        trustMgrFactory.init(keystore);

        // Load key manager
        KeyManagerFactory keyMgrFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        keyMgrFactory.init(keystore, password.toCharArray());

        // Create SSL context
        SSLContext ctx = SSLContext.getInstance("TLSv1.2");
        ctx.init(keyMgrFactory.getKeyManagers(), trustMgrFactory.getTrustManagers(), null);
        return ctx;
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}

希望这有帮助。
