android - 使用本地信任库时，Android HttpsUrlConnection javax.net.ssl.SSLException 连接因对等握手错误而关闭

Question

我无法让 AndroidOpenSSL使用该对象连接到一个简单的服务器HttpsUrlConnection（我已经梳理了 StackOverflow 和一堆在线教程，并且几乎逐行地按照示例进行操作，但我仍然无法弄清楚为什么我的当我使用本地信任库时损坏）。

我目前有一个尝试连接到简单的 Android 活动OpenSSL server（我可以使用 OpenSSL 客户端连接到我的服务器），一旦HttpsUrlConnection.connect()被调用，我就会收到一个“javax.net.ssl.SSLException: Connection closed by peer" error during the SSL handshake. 也许我错误地设置了我的示例服务器？

注意事项：

暂时没有客户授权
加载默认信任库时能够连接到https://www.google.com
无法使用自签名证书连接到本地主机上的服务器
不想信任所有证书
不想使用 Apache HttpClient
只想使用本地信任库
用充气城堡创建了本地信任库
能够正确地将信任库加载到
在代理防火墙后面，在我的 android 虚拟设备上设置了代理
AVD 设置为Android 4.1 API 16.

我已经尝试过的事情：

连接到两者127.0.0.1 and 10.0.2.2
使用新的SecureRandom() with the SSLContext.init()
创建网址'URL u = new URL("https", "10.0.2.2", 443, "/");'
使用TrustManagerFactory.getDefaultAlgorithms()而不是“X509”
- 给出"Unexpected response code error 503"而不是“连接被对等方关闭”

提前感谢您抽出宝贵时间查看我的问题！

使用命令启动的简单服务器：

$ sudo openssl s_server -accept 443 -cert server-cert.pem -key server-key.pem -pass file:passphrase.txt -state -www -verify 0

使用命令测试客户端连接：

$ openssl s_client -connect 127.0.0.1:443

Android 活动代码（已编辑以删除完整的运行代码以进行简化 - 如果需要更多代码，请告诉我） - 错误输出位于代码下方。

    try {
        TrustManagerFactory tmf;

        // local trust store
        tmf = TrustManagerFactory.getInstance("X509");
        tmf.init(loadLocalKeyStore(getApplicationContext()));

        // default trust store - works for https://www.google.com
        // tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        // tmf.init((KeyStore) null);

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

        HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.STRICT_HOSTNAME_VERIFIER;
        URL u = new URL("https://10.0.2.2");

        HttpsURLConnection urlConnection = (HttpsURLConnection) u.openConnection();

        urlConnection.setSSLSocketFactory(context.getSocketFactory());
        urlConnection.setHostnameVerifier(hostnameVerifier);
        urlConnection.connect();

        System.out.println("Response Code: " + urlConnection.getResponseCode());
        System.out.println("Response Code: " + urlConnection.getCipherSuite());
    } 

    ...

    private KeyStore loadLocalKeyStore(Context context) {
        InputStream in = context.getResources().openRawResource(R.raw.newserverkeystore);
        KeyStore trusted = null;
        try {
           trusted = KeyStore.getInstance("BKS");
           trusted.load(in, "thisisasecret".toCharArray());
        } finally {
           in.close();
        }
       return trusted;
    }

正确连接到https://www.google.com时的输出：

09-09 21:58:09.947: I/System.out(669): Response Code: 200
09-09 21:58:09.947: I/System.out(669): Response Code: TLS_ECDHE_RSA_WITH_RC4_128_SHA

尝试使用自签名证书连接到我的服务器时的输出：

我解决了我的问题 - 我需要使用 10.0.2.2 作为通用名称 (CN) 的证书，因此它匹配 Android localhost ip 地址 10.0.2.2 而不是“localhost”或“127.0.0.1”。

编辑：您可能可以创建一个证书，其中 localhost 作为 CN，“127.0.0.1”和“10.0.2.2”作为主题备用名称 (SAN)。

创建 10.0.2.2 证书和私钥 pem 文件后，我可以使用以下命令访问运行的服务器：

openssl s_server -accept 8888 -cert 10.0.2.2-cert.pem -key 10.0.2.2-key.pem  -state -www

如果您想强制客户端提供证书（尽管不会检查），请将标志添加-Verify 1到上面的命令中。

要在命令行测试服务器，您可以使用以下命令（注意 openssl 能够通过 127.0.0.1 连接）：

openssl s_client -connect 127.0.0.1:8888

如果服务器需要，要添加客户端证书，请添加标志-cert client-cert.pem -key client-key.pem

在我的 Android 客户端中，我使用以下代码进行连接（删除了错误检查）：

// use local trust store (CA)
TrustManagerFactory tmf;
KeyStore trustedStore = null;
InputStream in = context.getResources().openRawResource(R.raw.mycatruststore); // BKS in res/raw
trustedStore = KeyStore.getInstance("BKS");
trustedStore.load(in, "insertBksPasswordHere".toCharArray());
tmf = TrustManagerFactory.getInstance("X509");
tmf.init(trustedStore);

// load client certificate
KeyStore clientKeyStore = loadClientKeyStore(getApplicationContext());
KeyManagerFactory kmf = KeyManagerFactory.getInstance("X509");
kmf.init(clientKeyStore, "insertPasswordHere".toCharArray());

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

// provide client cert - if server requires client cert this will pass
context.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.STRICT_HOSTNAME_VERIFIER;

// connect to url
URL u = new URL("https://10.0.2.2:8888/");
HttpsURLConnection urlConnection = (HttpsURLConnection) u.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
urlConnection.setHostnameVerifier(hostnameVerifier);
urlConnection.connect();
System.out.println("Response Code: " + urlConnection.getResponseCode());

您应该得到一个 200 的响应代码，并且可以从那里解析响应。

这是加载客户端凭据的代码，这与加载服务器密钥库相同，但资源文件名和密码不同：

private KeyStore loadClientKeyStore(Context context) {
    InputStream in = context.getResources().openRawResource(R.yourKeyStoreFile);
    KeyStore trusted = null;
    trusted = KeyStore.getInstance("BKS");
    trusted.load(in, "yourClientPassword".toCharArray());
    in.close();
    return trusted;
}

我浪费了 6 - 7 个小时来解决这个问题，最后它与

public void URLConnection(String webUrl) throws IOException, NoSuchAlgorithmException, KeyManagementException {
        //TLSSocketFactory objTlsSocketFactory = new TLSSocketFactory();
        URL url = new URL(webUrl);
        HttpsURLConnection urlConnection = (HttpsURLConnection)url.openConnection();
        urlConnection.setRequestMethod("GET");
        //urlConnection.setSSLSocketFactory(objTlsSocketFactory);

        int responseCode = urlConnection.getResponseCode();
        System.out.println("\nSending 'GET' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);

        BufferedReader in = new BufferedReader(
                new InputStreamReader(urlConnection.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        //print result
        System.out.println(response.toString());
    }

它奏效了！！！！！！！
