Javax.net.ssl.SSLHandshakeException:javax.net.ssl.SSLProtocolException:SSL握手中止:SSL库失败,通常是协议错误

Question

我试图在android中运行以下代码

URLConnection l_connection = null;
        // Create connection
        uzip=new UnZipData(mContext);
        l_url = new URL(serverurl);

        if ("https".equals(l_url.getProtocol())) {
            System.out.println("<<<<<<<<<<<<< Before TLS >>>>>>>>>>>>");
            sslcontext = SSLContext.getInstance("TLS");
            System.out.println("<<<<<<<<<<<<< After TLS >>>>>>>>>>>>");
            sslcontext.init(null,
                    new TrustManager[] { new CustomTrustManager()},
                    new java.security.SecureRandom());
            HttpsURLConnection
                    .setDefaultHostnameVerifier(new CustomHostnameVerifier());
            HttpsURLConnection.setDefaultSSLSocketFactory(sslcontext
                    .getSocketFactory());

            l_connection = (HttpsURLConnection) l_url.openConnection();
            ((HttpsURLConnection) l_connection).setRequestMethod("POST");
        } else {
            l_connection = (HttpURLConnection) l_url.openConnection();
            ((HttpURLConnection) l_connection).setRequestMethod("POST");
        }
        /*System.setProperty("http.agent", "Android_Phone");*/


        l_connection.setConnectTimeout(10000);
        l_connection.setRequestProperty("Content-Language", "en-US");
        l_connection.setUseCaches(false);
        l_connection.setDoInput(true);
        l_connection.setDoOutput(true);
        System.out.println("<<<<<<<<<<<<< Before Connection >>>>>>>>>>>>");
        l_connection.connect();

在l_connection.connect(),它给出了这个SSLhandshakeException.有时候它有效,但大部分时间它都有例外.它只发生在Android 4.0模拟器上.我在Android 4.4和5.0上测试过,它运行正常.可能是什么原因造成的？请帮忙

Answer 1

我通过使用wireshark分析数据包找到了解决方案.我发现,在建立安全连接时,android 从TLSv1回退到SSLv3.这是Android版本<4.4中的一个错误,可以通过从Enabled Protocols列表中删除SSLv3协议来解决.我创建了一个名为NoSSLv3SocketFactory.java的自定义socketFactory类.使用它来制作一个socketfactory.

在连接时使用这样的类:

SSLContext sslcontext = SSLContext.getInstance("TLSv1");
sslcontext.init(null, null, null);
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());

HttpsURLConnection.setDefaultSSLSocketFactory(NoSSLv3Factory);
l_connection = (HttpsURLConnection) l_url.openConnection();
l_connection.connect();

更新:

现在,正确的解决方案是使用Google Play服务安装新的安全提供程序:

    ProviderInstaller.installIfNeeded(getApplicationContext());

这有效地使您的应用程序可以访问较新版本的OpenSSL和Java安全提供程序,其中包括对SSLEngine中的TLSv1.2的支持.安装新提供程序后,您可以通常的方式创建一个支持SSLv3,TLSv1,TLSv1.1和TLSv1.2的SSLEngine:

    SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
    sslContext.init(null, null, null);
    SSLEngine engine = sslContext.createSSLEngine();

或者您可以使用限制启用的协议engine.setEnabledProtocols.

不要忘记添加以下依赖项(此处的最新版本):

implementation 'com.google.android.gms:play-services-auth:17.0.0'

Answer 2

脚本

我在运行早于Android 5.0的Android版本的设备上获得了SSLHandSke例外.在我的用例中,我还想创建一个TrustManager来信任我的客户端证书.

我实现了NoSSLv3SocketFactory和NoSSLv3Factory从我的客户端支持的协议列表中删除SSLv3,但我无法使这两种解决方案都能正常工作.

我学到的一些东西:

• 在早于Android 5.0的设备上,默认情况下不启用TLSv1.1和TLSv1.2协议.
• 默认情况下,在早于Android 5.0的设备上未禁用SSLv3协议.
• SSLv3不是安全协议,因此需要在建立连接之前将其从客户端支持的协议列表中删除.

什么对我有用

Provider启动应用时,允许Android的安全性更新.

5.0+之前的默认提供程序不会禁用SSLv3.如果您可以访问Google Play服务,则从您的应用中修补Android安全提供程序相对简单.

private void updateAndroidSecurityProvider(Activity callingActivity) {
    try {
        ProviderInstaller.installIfNeeded(this);
    } catch (GooglePlayServicesRepairableException e) {
        // Thrown when Google Play Services is not installed, up-to-date, or enabled
        // Show dialog to allow users to install, update, or otherwise enable Google Play services.
        GooglePlayServicesUtil.getErrorDialog(e.getConnectionStatusCode(), callingActivity, 0);
    } catch (GooglePlayServicesNotAvailableException e) {
        Log.e("SecurityException", "Google Play Services not available.");
    }
}

如果您现在创建了OkHttpClient或HttpURLConnection,则TLSv1.1和TLSv1.2应作为协议提供,并且应删除SSLv3.如果在调用之前初始化了客户端/连接(或更具体地说是它的SSLContext)ProviderInstaller.installIfNeeded(...),则需要重新创建它.

不要忘记添加以下依赖项(此处的最新版本):

compile 'com.google.android.gms:play-services-auth:16.0.1'

资料来源:

• 使用ProviderInstaller Provider修补安全提供程序
• 使SSLEngine在Android上使用TLSv1.2(4.4.2)

在旁边

我不需要明确设置我的客户端应该使用哪些密码算法,但我发现SO帖子建议在编写时被认为最安全的那些:哪个Cipher套件启用SSL套接字？

Answer 3

此外,您应该知道您可以强制TLS v1.2用于默认情况下未启用它的Android 4.0设备:

这应该在您的应用程序的第一行:

try {
        ProviderInstaller.installIfNeeded(getApplicationContext());
        SSLContext sslContext;
        sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, null, null);
        sslContext.createSSLEngine();
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
            | NoSuchAlgorithmException | KeyManagementException e) {
        e.printStackTrace();
    }

Answer 4

以前,我也用自定义SSLFactory实现解决了这个问题,但根据OkHttp文档,解决方案更容易.

我TLS为4.2+设备提供所需密码的最终解决方案如下所示:

public UsersApi provideUsersApi() {

    private ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS)
        .supportsTlsExtensions(true)
        .tlsVersions(TlsVersion.TLS_1_2, TlsVersion.TLS_1_1, TlsVersion.TLS_1_0)
        .cipherSuites(
                CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
                CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
                CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256,
                CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,
                CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,
                CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,
                CipherSuite.TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,
                CipherSuite.TLS_ECDHE_ECDSA_WITH_RC4_128_SHA,
                CipherSuite.TLS_ECDHE_RSA_WITH_RC4_128_SHA,
                CipherSuite.TLS_DHE_RSA_WITH_AES_128_CBC_SHA,
                CipherSuite.TLS_DHE_DSS_WITH_AES_128_CBC_SHA,
                CipherSuite.TLS_DHE_RSA_WITH_AES_256_CBC_SHA)
        .build();

    OkHttpClient client = new OkHttpClient.Builder()
            .connectionSpecs(Collections.singletonList(spec))
            .build();

    return new Retrofit.Builder()
            .baseUrl(USERS_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build()
            .create(UsersApi.class);
}

请注意,支持的协议集取决于服务器上配置的协议.

Answer 5

我在此链接中找到了解决方案。

您只需要在Android应用程序类中的代码下方放置。这就足够了。无需在翻新设置中进行任何更改。它挽救了我的一天。

public class MyApplication extends Application {
@Override
public void onCreate() {
    super.onCreate();
    try {
      // Google Play will install latest OpenSSL 
      ProviderInstaller.installIfNeeded(getApplicationContext());
      SSLContext sslContext;
      sslContext = SSLContext.getInstance("TLSv1.2");
      sslContext.init(null, null, null);
      sslContext.createSSLEngine();
    } catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
        | NoSuchAlgorithmException | KeyManagementException e) {
        e.printStackTrace();
