Question

我现在正尝试使用双向SSL握手设置Netty，其中客户端和服务器都存在并验证证书。

这似乎没有在SslHandler中实现。有没有人这样做？我想它会进入SslHandler.handshake操作并被委托给javax.net.ssl.SSLEngine？

任何提示/提示/预先存在的实施？

谢谢！

ANSWER（stackoverflow不会让我以正常的方式发布它）我发现如果我在设置我的SslHandler之前在SSLEngine对象上设置了needClientAuth标志，那就解决了这个问题！

Answer 1

这是基于netty项目中的HttpSnoop服务器示例的解决方案。

设置客户端管道时，必须按如下方式设置ssl引擎：

public ChannelPipeline getPipeline() throws Exception {
    // Create a default pipeline implementation.
    ChannelPipeline pipeline = pipeline();

    // Uncomment the following line if you want HTTPS
    SSLEngine engine = SecureChatSslContextFactory.getServerContext().createSSLEngine();
    engine.setUseClientMode(false);
    engine.setNeedClientAuth(true);
    pipeline.addLast("ssl", new SslHandler(engine));

    pipeline.addLast("decoder", new HttpRequestDecoder());
    pipeline.addLast("logger", new RequestAuditLogger());
    // Uncomment the following line if you don't want to handle HttpChunks.
    pipeline.addLast("aggregator", new HttpChunkAggregator(1048576));
    pipeline.addLast("outputLogger", new ResponseAuditLogger());
    pipeline.addLast("encoder", new HttpResponseEncoder());
    // Remove the following line if you don't want automatic content compression.
    pipeline.addLast("deflater", new HttpContentCompressor());
    pipeline.addLast("handler", new HttpSnoopServerHandler());
    return pipeline;
}
}

然后，除了密钥库（SecureChatSslContextFactory）之外，还必须按如下方式修改SSLContext以设置信任存储：

public final class SecureChatSslContextFactory {


private static Logger logger = LoggerFactory.getLogger(SecureChatSslContextFactory.class);

private static final String PROTOCOL = "TLS";
private static final SSLContext SERVER_CONTEXT;
private static final SSLContext CLIENT_CONTEXT;

static {

    SSLContext serverContext = null;
    SSLContext clientContext = null;

        // get keystore and trustore locations and passwords
    String keyStoreLocation = System.getProperty("javax.net.ssl.keyStore");
    String keyStorePassword = System.getProperty("javax.net.ssl.keyStorePassword");
    String trustStoreLocation = System.getProperty("javax.net.ssl.trustStore");
    String trustStorePassword = System.getProperty("javax.net.ssl.trustStorePassword");
    try {

        KeyStore ks = KeyStore.getInstance("JKS");
        ks.load(KeyStoreStreamManager.asInputStream(keyStoreLocation),
                keyStorePassword.toCharArray());

        // Set up key manager factory to use our key store
        KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        kmf.init(ks, keyStorePassword.toCharArray());

          // truststore
        KeyStore ts = KeyStore.getInstance("JKS");
        ts.load(KeyStoreStreamManager.asInputStream(trustStoreLocation),
                trustStorePassword.toCharArray());

        // set up trust manager factory to use our trust store
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ts);

        // Initialize the SSLContext to work with our key managers.
        serverContext = SSLContext.getInstance(PROTOCOL);
        serverContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

    } catch (Exception e) {
        throw new Error(
                "Failed to initialize the server-side SSLContext", e);
    }

    try {
        clientContext = SSLContext.getInstance(PROTOCOL);
        clientContext.init(null, SecureChatTrustManagerFactory.getTrustManagers(), null);
    } catch (Exception e) {
        throw new Error(
                "Failed to initialize the client-side SSLContext", e);
    }

    SERVER_CONTEXT = serverContext;
    CLIENT_CONTEXT = clientContext;
}

public static SSLContext getServerContext() {
    return SERVER_CONTEXT;
}

public static SSLContext getClientContext() {
    return CLIENT_CONTEXT;
}

private SecureChatSslContextFactory() {
    // Unused
}
}

Answer 2

而不是设置SSLEngine使用nettys SslContext来创建新的SslHandler。基本上，您可以通过传递SslContext来创建新的KeyManagerFactory，如下所示

SslContext sslContext = SslContextBuilder.forServer（keyManagerFactory）.build（）;

然后使用创建的SslContext获取ChannelPipeline的处理程序。

ChannelPipeline.addLast（“ssl”，sslContext.newHandler（socketChannel.alloc（）））;

SslContext现在支持相互身份验证（目前仅适用于JDK提供商，但OpenSSL即将提供支持）。请参阅newClientContext和newServerContext，它们现在都支持使用TrustManagerFactory和KeyManagerFactory。这些静态工厂方法还支持直接获取证书，密钥和证书链文件，以便为您构建TrustManagerFactory和KeyManagerFactory。

有关如何要求客户端身份验证（对于JDK提供程序）的示例，请参阅JdkSslEngineTest。
