我正在尝试使用 Java 6 和 HTMLUnit 连接 SSL 站点https://link.bollore-logistics.com，我通过使用 Bouncy Castle 添加了更多受支持的密码。但是，我仍然收到握手失败。由于生产限制，我无法升级 Java 版本。请帮助

配置代码：

HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    });

    if (Security.getProvider("BC") == null){
        logger.info("Bouncy Castle provider is NOT available");
    }
    else{
        logger.info("Bouncy Castle provider is available");
    }

    Provider provider = new BouncyCastleProvider();
    Security.addProvider(provider);

    SSLContext context = SSLContext.getInstance("SSL");

    context.init(null, new X509TrustManager[]{new X509TrustManager() {

        @Override
        public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
        }

        @Override
        public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
        }

        @Override
        public X509Certificate[] getAcceptedIssuers() {
            return null;
        }
    }}, new SecureRandom());



    String[] scs = context.getSocketFactory().getSupportedCipherSuites();
    Arrays.sort(scs);

    for(String s : scs) {
        System.out.println(s);
     }
    HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());


    // Create all-trusting host name verifier
    HostnameVerifier allHostsValid = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };
    HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);

建立连接的代码（HTMLUnit）：

WebClient webClient = new WebClient(BrowserVersion.CHROME);
webClient.getOptions().setUseInsecureSSL(true);
webClient.getOptions().setRedirectEnabled(true);
webClient.getOptions().setThrowExceptionOnScriptError(false);
webClient.getOptions().setCssEnabled(false);
webClient.getOptions().setJavaScriptEnabled(true);
webClient.getPage(url);

这是错误日志：

我有一个类似的问题（但在这种情况下没有使用 HtmlUnit。我直接使用了 org.apache.http.impl.client.CloseableHttpClient）。

它接缝在java 7 之前的握手有问题（在 java 8 中不再有问题）。如果您尝试访问提供“TLSv1.2”的服务器，您可能会收到您报告的错误。

如果在您的情况下安全性不是那么大的问题，您可以尝试强制使用 TLSv1.1（只要您尚未切换到 java 8）。这应该是可能的：

   WebClientOptions webClientOptions= new WebClientOptions();
   webClientOptions.setSSLClientProtocols(new String[]{"TLSv1.1"});
   SSLConnectionSocketFactory.buildSSLSocketFactory(webClientOptions);

假设 Sun/Oracle Java 6，因为你没有说 IBM（它以不同的方式实现加密）：

您的问题不是密码（仅当问题是缺少 ECC 密码时，BC 提供者才能修复），也不是协议。https://www.ssllabs.com/ssltest/analyze.html?d=link.bollore-logistics.com表明服务器接受 Java 6 无需任何增强即可完成的密码和协议。

您的问题是 SNI（服务器名称指示）。ssllabs 报告显示，唯一失败的模拟客户端是那些不发送 SNI（Android 2、Windows XP、Java 6）的客户端，并且使用 openssl 进行的简单测试确认服务器需要 SNI。Java 6 JSSE 没有实现 SNI。

使用 JSSE 的 BC 版本可能会起作用——这是一个单独的 jarbctls-jdk15on-$ver不是bcprov-jdk15on-$ver和 providername BCJSSE 而不是 BC。根据来源，在最新版本（1.57 和 1.58）中，如果您使用域名（而不是 IP 地址或本地别名）进行连接，在我看来，客户端默认应该执行 SNI。但是我无法验证，因为由于 SecureRandom 的一些问题，我根本无法实例化 BCJSSE，我现在没有时间去追踪。
