Question

我正在开发一个需要通过HTTPS连接下载的Android应用程序。但我收到SSLHandshakeException - 握手失败。

我所做的如下

首先，使用openssl获取服务器证书链

openssl s_client -connect www.coles.com.au:443

得到了

Certificate chain
 0 s:/C=AU/ST=Victoria/L=Hawthorn East/O=Coles Supermarkets Australia Pty Ltd/OU=Web Team/CN=coles.com.au
   i:/C=US/O=thawte, Inc./CN=thawte SSL CA - G2
 1 s:/C=US/O=thawte, Inc./CN=thawte SSL CA - G2
   i:/C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c) 2006 thawte, Inc. - For authorized use only/CN=thawte Primary Root CA

然后去解冻网站（https://search.thawte.com/support/ssl-digital-certificates/index?page=content&id=SO26817&actp=RSS&viewlocale=en_US#links）下载CA证书（告诉我，如果我做错了或从错误的地方下载），这是thawte_SSL_CA_G2.cer

第三，我有以下代码连接

String url = "https://www.coles.com.au";
        String strContent = "";
        HttpURLConnection connection;

        AssetManager assetManager = context.getAssets();
        InputStream caInput = null;

        try{
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            caInput = assetManager.open("thawte_SSL_CA_G2.cer");
            Certificate ca = cf.generateCertificate(caInput);

            String keyStoreType = KeyStore.getDefaultType();
            KeyStore keyStore = KeyStore.getInstance(keyStoreType);
            keyStore.load(null, null);
            keyStore.setCertificateEntry("ca", ca);

            String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
            TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
            tmf.init(keyStore);

            SSLContext context = SSLContext.getInstance("TLS");
            context.init(null, tmf.getTrustManagers(), null);

            URL urlObj = new URL(url);

            HttpsURLConnection urlConnection =
                    (HttpsURLConnection)urlObj.openConnection();
            urlConnection.setSSLSocketFactory(context.getSocketFactory());
            InputStream in = urlConnection.getInputStream();

            BufferedReader reader = new BufferedReader(new InputStreamReader(in));

            while(null != (strContent= reader.readLine())){
                System.out.println(strContent);
            }
        }
        catch (IOException e){
             String exception = e.getMessage();
            System.out.println(exception);
        }

我使用wireshark捕获并观察下面发生的事情

-> Client Hello
<- Server Hello
<- Certificate
<- Server Key Exchange
-> Client Key Exchange, Change Cipher Spec, Hello Request, Hello Request
<- FIN

请帮我解释为什么握手失败。

Answer 1

您应该添加所有ICA（中间证书）和CA.

您可以执行以下操作

openssl s_client -showcerts -connect  www.coles.com.au:443

将您收到的所有证书添加到信任库。（严格来说，信托商店只有ICA和CA就足够了）

SSLHandshakeException - Android 6.0上的握手失败
