Java1.6_45+；BouncyCastle+；TLS1.2抛出握手失败（40）（通知安全重新协商）

我的案子几乎快结束了

我在JDK1.6_u45上尝试使用BouncyCastle连接到TLS1.2上的https端点。 我已经在jre/lib/security下的cacerts中添加了端点公钥证书

但是，我得到的错误遵循不同的堆栈跟踪，如下所示：

BouncyCastle TLSSocketConnectionFactory与此链接中提供的工厂相同，因此我不再在此发布。（链接：

我的测试等级如下：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

import javax.net.ssl.HttpsURLConnection;

import com.google.gson.Gson;

public class CopyOfTest {
    public static void main(String[] args) throws IOException, Exception {
        //below url is a not an actual endpoint. 
        URL url = new URL(
                "https://abc.def.ghi/Customer/v1/nonexistantlink/?postalCode=80120&clientId=ABC");
        String returnData = getResponseJsonString(url);
        System.out.println("returnData: " + returnData);
        ArrayNameDescDTO msg = new Gson().fromJson(returnData,
                ArrayNameDescDTO.class);
        System.out.println(msg.toString());


    }

    private static String getResponseJsonString(URL url) throws IOException {

//      Security.addProvider(new BouncyCastleJsseProvider());
//       SSLContext sslcontext = SSLContext.getInstance("TLS",new BouncyCastleJsseProvider())

        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setSSLSocketFactory(new TLSSocketConnectionFactory());

        conn.setRequestMethod("GET");
        byte[] message = ("username" + ":" + "andItsPassword").getBytes("UTF-8");
        String encoded = javax.xml.bind.DatatypeConverter.printBase64Binary(message);
        System.out.println("encoded: Basic " + encoded);
        conn.setRequestProperty("Authorization", "Basic " + encoded);
        conn.setConnectTimeout(10000); // 10 sec

        conn.connect();
        int status = conn.getResponseCode();
        if (conn.getResponseCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : "
                    + conn.getResponseCode());
        }
        switch (status) {
        case 200:
        case 201:
            BufferedReader br = new BufferedReader(new InputStreamReader(
                    conn.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line + "\n");
            }
            br.close();
            conn.disconnect();
            return sb.toString();
        }

        conn.disconnect();
        return null;

    }
}

有任何建议或建议吗？

此解决方案由@James restore Monica Polk提供。我将此解决方案重新发布在此处，以便其他人可以从中受益

解决方案是创建一个新的TLS客户端，该客户端扩展“org.bouncycastle.crypto.TLS.DefaultTlsClient”并覆盖“notifySecureRenegotiation”方法。 如下所示：

import org.bouncycastle.crypto.tls.DefaultTlsClient;

public class NewDefaultTlsClient extends DefaultTlsClient{

    @Override
    public void notifySecureRenegotiation(boolean secureRenegotiation){
        //do nothing here
    }

    @Override
    public org.bouncycastle.crypto.tls.TlsAuthentication getAuthentication()
            throws IOException {
        // TODO Auto-generated method stub
        return null;
    }

}

现在，在TLSSocketConnectionFactory上，转到startAndShake（）方法，并更改

tlsClientProtocol.connect(new DefaultTlsClient(){ ....

就是这样！在上述更改之后，上述错误停止显示，JDK6代码能够命中TLS1.2端点。

您使用的是什么版本的bouncycastle库？BC源代码和RFC 5246有点慢，但看起来服务器不支持安全重新协商。TLS 1要求这样做。2规范，因此BC TLS客户端中止握手。我尝试了“bcprov-jdk15on-164”和“bcprov-jdk16-1.46”两种方法。最终得到了相同的错误。我在这个网站上找到了关于RFC 5746的一些信息：“”。这里的人说“只需在客户端中重写“notifySecureRenegotiation”方法，而在该方法中什么都不做”但是TLSSocketConnectionFactory似乎没有这个方法可以重写，所以我很困惑OP是在哪里添加这个重写方法来让它为他工作的。我想你可以在你的method您将看到BC tls协议实例是以

DefaultTlsClient

的实例启动的。您需要子类化

DefaultTlsClient

以覆盖

notifySecureRenegotiation（）

方法。

tlsClientProtocol.connect(new NewDefaultTlsClient(){ ....
