Android pre-lollipop设备发出错误“SSL握手中止：ssl = 0x618d9c18：系统调用期间的I / O错误，同级连接重置”

问题描述 投票：14回答：5

我有这个奇怪的问题，其中改造不断抛弃我

“SSL握手中止：ssl = 0x618d9c18：系统调用期间的I / O错误，同级连接重置”

在kitkat，而相同的代码在棒棒糖设备中工作正常。我使用如下的OkHttpClient客户端

public OkHttpClient getUnsafeOkHttpClient() {
    try {
        final TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
            @Override
            public void checkClientTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) {
            }
            @Override
            public void checkServerTrusted(
                    java.security.cert.X509Certificate[] chain,
                    String authType) {
            }
            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return new java.security.cert.X509Certificate[0];
            }
        } };

        int cacheSize = 10 * 1024 * 1024; // 10 MB
        Cache cache = new Cache(getCacheDir(), cacheSize);
        final SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
        sslContext.init(null, trustAllCerts,
                new java.security.SecureRandom());
        final SSLSocketFactory sslSocketFactory = sslContext
                .getSocketFactory();
        OkHttpClient okHttpClient = new OkHttpClient();
        okHttpClient = okHttpClient.newBuilder()
                .cache(cache)
                .sslSocketFactory(sslSocketFactory)
                .hostnameVerifier(org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER).build();
        return okHttpClient;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }

}

我在这样的改造中使用这个客户端

Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(getUnsafeOkHttpClient())
            .addConverterFactory(GsonConverterFactory.create())
            .build();

编辑：添加getUnsafeOkHttpClient()在这里没有任何影响，并没有建议通过使用getUnsafeOkHttpClient()绕过ssl检查

仅供参考：问题是因为api端点仅支持在Android设备TLS 1.2上默认禁用的16<device<20。因此，对于16<device<20，创建一个自定义SSLSocketFactory

终于找到了解决这个问题的方法，它不是一个完整的解决方案，因为它是来自okhttp，square Jesse Wilson的here提到的黑客攻击。正如我所提到的，这是一个简单的黑客，我必须将我的SSLSocketFactory变量重命名为

private SSLSocketFactory delegate;

请注意，如果您提供除委托之外的任何名称，则会抛出错误。我在下面发布完整的解决方案

这是我的TLSSocketFactory类

public class TLSSocketFactory extends SSLSocketFactory {

private SSLSocketFactory delegate;

public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, null, null);
    delegate = context.getSocketFactory();
}

@Override
public String[] getDefaultCipherSuites() {
    return delegate.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return delegate.getSupportedCipherSuites();
}

@Override
public Socket createSocket() throws IOException {
    return enableTLSOnSocket(delegate.createSocket());
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort));
}

private Socket enableTLSOnSocket(Socket socket) {
    if(socket != null && (socket instanceof SSLSocket)) {
        ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}

}

这就是我用okhttp和改造它的方式

 OkHttpClient client=new OkHttpClient();
    try {
        client = new OkHttpClient.Builder()
                .sslSocketFactory(new TLSSocketFactory())
                .build();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(client)
            .addConverterFactory(GsonConverterFactory.create())
            .build();

我在这里获得了api.data.gov.in的SSL / TLS信息 - https://www.ssllabs.com/ssltest/analyze.html?d=api.data.gov.in

它看起来只支持TLSv1.2。旧的Android版本确实存在最新TLS版本的问题。在ssllabs页面的“握手模拟”部分，您甚至可以看到您的问题。

有关可用的解决方案，请参阅How to enable TLS 1.2 support in an Android application (running on Android 4.1 JB)。

我修改了@Navneet Krishna的答案因为方法OkHttpClient.Builder。 builder.sslSocketFactory（tlsSocketFactory）现已弃用。

public class TLSSocketFactory extends SSLSocketFactory {

private final SSLSocketFactory delegate;
private TrustManager[] trustManagers;

@Inject
public TLSSocketFactory() throws KeyStoreException, KeyManagementException, NoSuchAlgorithmException {
    generateTrustManagers();
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, trustManagers, null);
    delegate = context.getSocketFactory();
}

private void generateTrustManagers() throws KeyStoreException, NoSuchAlgorithmException {
    TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    trustManagerFactory.init((KeyStore) null);
    TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();

    if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
        throw new IllegalStateException("Unexpected default trust managers:"
                + Arrays.toString(trustManagers));
    }

    this.trustManagers = trustManagers;
}

@Override
public String[] getDefaultCipherSuites() {
    return delegate.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return delegate.getSupportedCipherSuites();
}

@Override
public Socket createSocket() throws IOException {
    return enableTLSOnSocket(delegate.createSocket());
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return enableTLSOnSocket(delegate.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return enableTLSOnSocket(delegate.createSocket(address, port, localAddress, localPort));
}

private Socket enableTLSOnSocket(Socket socket) {
    if (socket instanceof SSLSocket) {
        ((SSLSocket) socket).setEnabledProtocols(new String[]{"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}

@Nullable
public X509TrustManager getTrustManager() {
    return  (X509TrustManager) trustManagers[0];
}
}

您需要像这样分配：

TLSSocketFactory tlsTocketFactory = new TLSSocketFactory();
client = new OkHttpClient.Builder()
            .sslSocketFactory(tlsSocketFactory, tlsSocketFactory.getTrustManager());
            .build();

除了Navneet Krishna，我不得不在我的App课程中做下一个：

ProviderInstaller.installIfNeededAsync

根据https://developer.android.com/training/articles/security-gms-provider，这是因为我需要更新安全提供程序以防止SSL攻击。

我的应用类：

public class AppClass extends MultiDexApplication {

private static final String TAG = AppClass.class.getName();

private static Context context;
private static AuthAPI authAPI;
private static RestAPI buyersAPI;

@Override
public void onCreate() {
    super.onCreate();
    /* enable SSL compatibility in pre-lollipop devices */
    upgradeSecurityProvider();

    createAuthAPI();
    createRestAPI();
}

private void upgradeSecurityProvider() {
    try{
        ProviderInstaller.installIfNeededAsync(this, new ProviderInstaller.ProviderInstallListener() {
            @Override
            public void onProviderInstalled() {
                Log.e(TAG, "New security provider installed.");
            }

            @Override
            public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {
                GooglePlayServicesUtil.showErrorNotification(errorCode, BuyersApp.this);
                Log.e(TAG, "New security provider install failed.");
            }
        });
    }catch (Exception ex){
        Log.e(TAG, "Unknown issue trying to install a new security provider", ex);
    }

}

private void createAuthAPI() {
    OkHttpClient.Builder authAPIHttpClientBuilder = new OkHttpClient.Builder();

    Retrofit retrofit = new Retrofit.Builder()
            .client(enableTls12OnPreLollipop(authAPIHttpClientBuilder).build())
            .baseUrl(DomainLoader.getInstance(context).getAuthDomain())
            .addConverterFactory(GsonConverterFactory.create())
            .build();
    authAPI = retrofit.create(AuthAPI.class);
}

private static OkHttpClient.Builder enableTls12OnPreLollipop(OkHttpClient.Builder client) {
    if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 22) {
        try {
            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);

            TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(
                    TrustManagerFactory.getDefaultAlgorithm());
            trustManagerFactory.init((KeyStore) null);
            TrustManager[] trustManagers = trustManagerFactory.getTrustManagers();
            if (trustManagers.length != 1 || !(trustManagers[0] instanceof X509TrustManager)) {
                throw new IllegalStateException("Unexpected default trust managers:"
                        + Arrays.toString(trustManagers));
            }
            X509TrustManager trustManager = (X509TrustManager) trustManagers[0];

            client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()), trustManager);

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2)
                    .build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);
            specs.add(ConnectionSpec.CLEARTEXT);

            client.connectionSpecs(specs);
        } catch (Exception exc) {
            Log.e("OkHttpTLSCompat", "Error while setting TLS 1.2", exc);
        }
    }

    return client;
}

private void createRestAPI() {
    OkHttpClient.Builder restAPIHttpClientBuilder = new OkHttpClient.Builder();
    buyersAPIHttpClientBuilder.readTimeout(60, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.connectTimeout(60, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.writeTimeout(600, TimeUnit.SECONDS);
    buyersAPIHttpClientBuilder.addInterceptor(new NetworkErrorInterceptor());
    buyersAPIHttpClientBuilder.addInterceptor(new TokenVerificationInterceptor());

    Retrofit retrofit = new Retrofit.Builder()
            .client(enableTls12OnPreLollipop(restAPIHttpClientBuilder).build())
            .baseUrl(DomainLoader.getInstance(context).getDomain())
            .addConverterFactory(GsonConverterFactory.create(new GsonBuilder().setLenient().create()))
            .addConverterFactory(ScalarsConverterFactory.create())
            .build();

    buyersAPI = retrofit.create(RestAPI.class);
}
}

和我的Tls12SocketFactory类：

public class Tls12SocketFactory extends SSLSocketFactory {
private static final String[] TLS_V12_ONLY = {"TLSv1.2"};

final SSLSocketFactory delegate;

public Tls12SocketFactory(SSLSocketFactory base) {
    this.delegate = base;
}

@Override
public String[] getDefaultCipherSuites() {
    return delegate.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return delegate.getSupportedCipherSuites();
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return patch(delegate.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return patch(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return patch(delegate.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return patch(delegate.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return patch(delegate.createSocket(address, port, localAddress, localPort));
}

private Socket patch(Socket s) {
    if (s instanceof SSLSocket) {
        ((SSLSocket) s).setEnabledProtocols(TLS_V12_ONLY);
    }
    return s;
}
}

它在KitKat及以上版本的所有设备中都具有魅力。

我认为我的解决方案可以帮助某人。

在我的项目中，我需要在较旧的Android（4.4）上通过SSL执行JSON请求，并且我一直在线程顶部提到问题。

要修复它，我所要做的就是完全按照上面的方式添加类Tls12SocketFactory。

但是，我在项目类中添加了修改后的代码

我把它添加到我的oncreate

upgradeSecurityProvider();

并修改了上下文的功能，这就是全部。不再有SSL连接问题

private void upgradeSecurityProvider() {
        try{
            ProviderInstaller.installIfNeededAsync(this, new ProviderInstaller.ProviderInstallListener() {
                @Override
                public void onProviderInstalled() {
                    Log.e("SSLFix", "New security provider installed.");
                }

                @Override
                public void onProviderInstallFailed(int errorCode, Intent recoveryIntent) {
                   // GooglePlayServicesUtil.showErrorNotification(errorCode, BuyersApp.this);
                    Log.e("SSLFix", "New security provider install failed.");
                }
            });
        }catch (Exception ex){
            Log.e("SSLFix", "Unknown issue trying to install a new security provider", ex);
        }

}

这就是全部而且不再是问题。
