Android HttpsUrlConnection javax.net.ssl.SSLException使用本地信任库时,由对等握手错误关闭连接

Question

我OpenSSL使用该HttpsUrlConnection对象让Android连接到一个简单的服务器时遇到了麻烦(我已经通过StackOverflow和一堆在线教程进行了梳理,并按照示例进行了大量的线条,我仍然无法弄清楚为什么我的当我使用我的本地信任库时,它被破坏了.

我目前有一个Android活动试图连接到一个简单的OpenSSL server(我可以使用OpenSSL客户端连接到我的服务器),一旦HttpsUrlConnection.connect()被调用我收到" javax.net.ssl.SSLException: Connection closed by peer" error during the SSL handshake. 也许我正在设置我的样本服务器错误？

注意事项:

• 目前没有客户授权
• 我可以在加载默认信任库时连接到https://www.google.com
• 无法使用自签名证书连接到localhost上的服务器
• 不想信任所有证书
• 不想使用Apache HttpClient
• 想只使用本地信任库
• 用充气城堡创建了本地信托商店
• 我能够正确加载信任库
• 在代理防火墙后面,代理在我的android虚拟设备上设置
• 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()
• 使用创建URL '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"由同伴关闭的连接"

提前感谢您抽出宝贵时间来审核我的问题!

使用命令启动简单服务器:

$ 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(编辑后删除完整的运行代码以简化 - 如果需要更多代码,请告诉我) - 错误输出低于代码.

    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输出:

Answer 1

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,因此它与10.0.2.2的Android localhost ip地址匹配,而不是'localhost'或'127.0.0.1'.

编辑:您可能创建一个证书,localhost作为CN,'127.0.0.1'和'10 .0.2.2'作为主题备用名称(SAN).

一旦我创建了10.0.2.2 cert和私钥pem文件,我就可以使用以下命令运行我的服务器:

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

如果要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,您可以使用以下内容(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200的响应代码,并可以从那里剖析响应.

这是加载客户端凭据的代码,与加载服务器密钥库但使用不同的资源文件名和密码相同:

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;
}
