Java：通过资源加载SSL密钥库

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war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。）

---

现在，如果我打开相同的连接，我会得到：

javax.net.ssl.SSLHandshakeException:Received fatal alert:handshake\u 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。希望我所做的能帮助你

首先，我必须创建一个信托经理：

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();
    }
}

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();
    }
}

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 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();
    }
}

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();
    }
}

然后我用那个插座工厂发了我的帖子：

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将证书文件添加到常规密钥库中。我在研究过程中发现的所有示例源代码都指向创建套接字因子，然后向该套接字工厂注册协议。也许有一种方法可以简单地使用套接字工厂进行连接，而无需注册协议；我还没有彻底调查过。在我的特殊情况下，制定一个特定的协议是必要的。希望这能让你在这条路上走得更远。我承认这似乎有点迂回；我一开始也有同样的感觉。但这是我让它工作的唯一方法。也许其他人有更好的解决方案。

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.mysslssocketfactory

是实现

org.apache.axis.components.net.SecureSocketFactory

（您可以扩展

org.apache.axis.components.net.JSSESocketFactory

）

---

在

create

方法中，使用从您配置的

SSLContext

中获得的套接字工厂创建套接字。

为了子孙后代，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");
}

---

如果需要，这里有一个API可以轻松创建SSLSocket和SSLServerSocket：

它不需要任何其他罐子。。。。只需获取文件并像以下那样使用它们：

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

或：

---

这更容易使用：）

我遇到了类似的问题，我解决了创建一个函数的问题，该函数使用来自和输入流的密钥库返回SSL上下文

   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;
}

希望这能有所帮助。

然后您将如何使用

SSLContext

实例

sc

？您是否使用它来创建一个

SocketFactory

，并将其设置到建立连接的对象中？我没有用它做任何事情。我正在使用Axis连接到web服务。记住关闭FileInputStream，KeyStore的javadoc中的示例代码显式关闭了它。我遇到了类似的问题，在设置系统属性后，我得到了：原因：sun.security.validator.ValidatorException:PKIX路径生成失败：sun.security.provider.certpath.SunCertPathBuilderException:无法在上找到请求目标的有效认证路径sun.security.validator.PKIXValidator.doBuild（PKIXValidator.java:323）位于sun.security.validator.PKIXValidator.engineValidate（PKIXValidator.java:217）有什么想法吗？“如果（环境=='production'）{…System.setProperty（“sun.security.ssl.allowunsaferencation”，“true”）；”-我真的希望这是一个输入错误：-/。您给出的一行代码解决了问题，然后由开发人员实现自定义SecureSocketFactory。
