【中文标题】如何在 Android 应用程序中启用 TLS 1.2 支持(在 Android 4.1 JB 上运行)【英文标题】:How to enable TLS 1.2 support in an Android application (running on Android 4.1 JB) 【发布时间】:2015-05-10 16:57:54 【问题描述】:根据 android 中针对 SSLSocket
和 SSLContext
的文档,API 级别 16+ 支持 TLS v1.1 和 v1.2 协议,但默认情况下不启用。
http://developer.android.com/reference/javax/net/ssl/SSLSocket.html
http://developer.android.com/reference/javax/net/ssl/SSLContext.html
如何在运行 Android 4.1 或更高版本(但低于 5.0)的设备上启用它?
我尝试创建一个自定义 SSLSocketFactory,它在创建 Socket
时启用所有受支持的协议,然后将我的自定义实现用作:
HttpsURLConnection.setDefaultSSLSocketFactory(new MySSLSocketFactory());
public class MySSLSocketFactory extends SSLSocketFactory
private SSLContext sc;
private SSLSocketFactory ssf;
public MySSLSocketFactory()
try
sc = SSLContext.getInstance("TLS");
sc.init(null, null, null);
ssf = sc.getSocketFactory();
catch (NoSuchAlgorithmException e)
e.printStackTrace();
catch (KeyManagementException e)
e.printStackTrace();
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose)
throws IOException
SSLSocket ss = (SSLSocket) ssf.createSocket(s, host, port, autoClose);
ss.setEnabledProtocols(ss.getSupportedProtocols());
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
return ss;
@Override
public String[] getDefaultCipherSuites()
return ssf.getDefaultCipherSuites();
@Override
public String[] getSupportedCipherSuites()
return ssf.getSupportedCipherSuites();
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException
SSLSocket ss = (SSLSocket) ssf.createSocket(host, port);
ss.setEnabledProtocols(ss.getSupportedProtocols());
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
return ss;
@Override
public Socket createSocket(InetAddress host, int port) throws IOException
SSLSocket ss = (SSLSocket) ssf.createSocket(host, port);
ss.setEnabledProtocols(ss.getSupportedProtocols());
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
return ss;
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort)
throws IOException, UnknownHostException
SSLSocket ss = (SSLSocket) ssf.createSocket(host, port, localHost, localPort);
ss.setEnabledProtocols(ss.getSupportedProtocols());
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
return ss;
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress,
int localPort) throws IOException
SSLSocket ss = (SSLSocket) ssf.createSocket(address, port, localAddress, localPort);
ss.setEnabledProtocols(ss.getSupportedProtocols());
ss.setEnabledCipherSuites(ss.getSupportedCipherSuites());
return ss;
但在尝试与启用了仅 TLS 1.2 的服务器建立连接时,它仍然会出现异常。
这是我得到的例外:
03-09 09:21:38.427: W/System.err(2496): javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException:SSL 握手中止: ssl=0xb7fa0620: SSL 库失败,通常是协议错误
03-09 09:21:38.427: W/System.err(2496): 错误:14077410:SSL 例程:SSL23_GET_SERVER_HELLO:sslv3 警报握手失败 (外部/openssl/ssl/s23_clnt.c:741 0xa90e6990:0x00000000)
【问题讨论】:
在我的测试中,我发现虽然 TLSv1.2 可用并且可以在 API 16-18 上启用,但在提供客户端证书等特定用途方面仍然存在问题,即使在包含 Play Services 之后也是如此。还没有解决方案。 更令人困惑的是 SSLEngine 声明对 TLS1.1/1.2 的支持仅在 API20+ 中。 developer.android.com/reference/javax/net/ssl/SSLEngine.html 【参考方案1】:你应该使用
SSLContext.getInstance("TLSv1.2");
具体协议版本。
第二个异常发生是因为默认的 socketFactory 使用了备用 SSLv3 协议来处理故障。
您可以在此处使用主要答案中的 NoSSLFactory 来抑制 How to disable SSLv3 in android for HttpsUrlConnection?
您还应该使用所有证书(如果需要,客户端和受信任的证书)初始化 SSLContext
但如果不使用,所有这些都是无用的
ProviderInstaller.installIfNeeded(getContext())
这里有更多关于正确使用场景的信息https://developer.android.com/training/articles/security-gms-provider.html
希望对你有帮助。
【讨论】:
据此 - grepcode.com/file/repo1.maven.org/maven2/org.ektorp/… - 仅接受"TLS"
、"SSL"
和 "SSLV2"
。
这似乎无法解决 4.1.2 客户端的问题
也许这很愚蠢,但我尝试将 4.0.1.2 版本中的 com.google.android lib 添加到我的 gradle 中,但我无法导入 com.google.android.gms.security.* 所以从哪个包你导入ProviderInstaller?【参考方案2】:
启用 TLSv1.1 和 TLSv1.2 的两种方法:
-
使用此指南:
http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/
使用这个类
https://github.com/erickok/transdroid/blob/master/app/src/main/java/org/transdroid/daemon/util/TlsSniSocketFactory.java
schemeRegistry.register(new Scheme("https", new TlsSniSocketFactory(), port));
【讨论】:
我使用了您的第二个建议,但我遇到了问题。在 TlsSniSocketFactory 类的 createSocket() 方法中,返回的 SSL Session 无效。我不知道为什么,但这发生在 API 17 和 API 24 设备中?请查看我的详细查询:***.com/questions/40684898/… 非常感谢!这为我节省了很多时间! 使用第一个选项,使用 httpclient,但 v1.0 变旧,实际上想要 v1.2。私有 HttpClient getTheHttpClient(HttpParams httpParameters) SchemeRegistry registry = new SchemeRegistry();尝试 registry.register(new Scheme("https", new TLSSocketFactory(), 443)); 捕捉 (KeyManagementException e) e.printStackTrace(); catch (NoSuchAlgorithmException e) e.printStackTrace(); HttpClient 客户端 = new DefaultHttpClient(new ThreadSafeClientConnManager(httpParameters, registry),httpParameters);返回客户; 【参考方案3】:@Inherently Curious - 感谢您发布此信息。您快到了 - 您必须向 SSLContext.init() 方法添加另外两个参数。
TrustManager[] trustManagers = new TrustManager[] new TrustManagerManipulator() ;
sc.init(null, trustManagers, new SecureRandom());
它将开始工作。再次非常感谢您发布此信息。我用你的代码解决了这个/我的问题。
【讨论】:
我一定是错过了,但是 TrustManagerManipulator 类是从哪里来的呢?【参考方案4】:我按照文章http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ 中提供的指示解决了这个问题,几乎没有改变。
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
SSLSocketFactory noSSLv3Factory = null;
if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.KITKAT)
noSSLv3Factory = new TLSSocketFactory(sslContext.getSocketFactory());
else
noSSLv3Factory = sslContext.getSocketFactory();
connection.setSSLSocketFactory(noSSLv3Factory);
这是自定义TLSSocketFactory的代码:
public static class TLSSocketFactory extends SSLSocketFactory
private SSLSocketFactory internalSSLSocketFactory;
public TLSSocketFactory(SSLSocketFactory delegate) throws KeyManagementException, NoSuchAlgorithmException
internalSSLSocketFactory = delegate;
@Override
public String[] getDefaultCipherSuites()
return internalSSLSocketFactory.getDefaultCipherSuites();
@Override
public String[] getSupportedCipherSuites()
return internalSSLSocketFactory.getSupportedCipherSuites();
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
@Override
public Socket createSocket(InetAddress host, int port) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
/*
* Utility methods
*/
private static Socket enableTLSOnSocket(Socket socket)
if (socket != null && (socket instanceof SSLSocket)
&& isTLSServerEnabled((SSLSocket) socket)) // skip the fix if server doesn't provide there TLS version
((SSLSocket) socket).setEnabledProtocols(new String[]TLS_v1_1, TLS_v1_2);
return socket;
private static boolean isTLSServerEnabled(SSLSocket sslSocket)
System.out.println("__prova__ :: " + sslSocket.getSupportedProtocols().toString());
for (String protocol : sslSocket.getSupportedProtocols())
if (protocol.equals(TLS_v1_1) || protocol.equals(TLS_v1_2))
return true;
return false;
编辑:感谢 ademar111190 的 kotlin 实现 (link)
class TLSSocketFactory constructor(
private val internalSSLSocketFactory: SSLSocketFactory
) : SSLSocketFactory()
private val protocols = arrayOf("TLSv1.2", "TLSv1.1")
override fun getDefaultCipherSuites(): Array<String> = internalSSLSocketFactory.defaultCipherSuites
override fun getSupportedCipherSuites(): Array<String> = internalSSLSocketFactory.supportedCipherSuites
override fun createSocket(s: Socket, host: String, port: Int, autoClose: Boolean) =
enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose))
override fun createSocket(host: String, port: Int) =
enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))
override fun createSocket(host: String, port: Int, localHost: InetAddress, localPort: Int) =
enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort))
override fun createSocket(host: InetAddress, port: Int) =
enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port))
override fun createSocket(address: InetAddress, port: Int, localAddress: InetAddress, localPort: Int) =
enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort))
private fun enableTLSOnSocket(socket: Socket?) = socket?.apply
if (this is SSLSocket && isTLSServerEnabled(this))
enabledProtocols = protocols
private fun isTLSServerEnabled(sslSocket: SSLSocket) = sslSocket.supportedProtocols.any it in protocols
【讨论】:
嗨,它对我不起作用,知道为什么吗?如果您能提供帮助,那就太好了 我已经使用你的答案来建立 MQTT SSL 连接,它工作得很好!谢谢你。 #UP @StoicaMircea 这实际上将使用无 ssl 进行连接。这是不安全的。你可以在这里使用我的解决方法:***.com/questions/47410689/… @AmirZiarati ,我后来发现你是对的。我也从TLS_v1_1, TLS_v1_2
切换到 TLS_v1_2, TLS_v1_1
,首先尝试使用 TLS 1.2
好点 ;) 谢谢。我会根据您的建议编辑我的答案。【参考方案5】:
我对上述答案有一些补充 它实际上是来自 okhttp 的 Jesse Wilson 提到的 hack,正方形 here。根据这个 hack,我不得不将我的 SSLSocketFactory 变量重命名为
private SSLSocketFactory delegate;
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;
这就是我在 okhttp 和改造中使用它的方式
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();
【讨论】:
这是我得到的最有帮助的答案。谢谢,兄弟。【参考方案6】:正如 OP 所说,TLS v1.1 和 v1.2 协议在 API 级别 16+ 中支持,但默认不启用,我们只需要启用它即可。
此处的示例使用HttpsUrlConnection
,而不是HttpUrlConnection
。关注https://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/,我们可以创建工厂
class MyFactory extends SSLSocketFactory
private javax.net.ssl.SSLSocketFactory internalSSLSocketFactory;
public MyFactory() throws KeyManagementException, NoSuchAlgorithmException
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, null, null);
internalSSLSocketFactory = context.getSocketFactory();
@Override
public String[] getDefaultCipherSuites()
return internalSSLSocketFactory.getDefaultCipherSuites();
@Override
public String[] getSupportedCipherSuites()
return internalSSLSocketFactory.getSupportedCipherSuites();
@Override
public Socket createSocket() throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket());
@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
@Override
public Socket createSocket(InetAddress host, int port) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException
return enableTLSOnSocket(internalSSLSocketFactory.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;
无论您使用哪个网络库,请确保调用 ((SSLSocket)socket).setEnabledProtocols(new String[] "TLSv1.1", "TLSv1.2");
,以便 Socket 启用 TLS 协议。
现在,您可以在 HttpsUrlConnection
中使用它
class MyHttpRequestTask extends AsyncTask<String,Integer,String>
@Override
protected String doInBackground(String... params)
String my_url = params[0];
try
URL url = new URL(my_url);
HttpsURLConnection httpURLConnection = (HttpsURLConnection) url.openConnection();
httpURLConnection.setSSLSocketFactory(new MyFactory());
// setting the Request Method Type
httpURLConnection.setRequestMethod("GET");
// adding the headers for request
httpURLConnection.setRequestProperty("Content-Type", "application/json");
String result = readStream(httpURLConnection.getInputStream());
Log.e("My Networking", "We have data" + result.toString());
catch (Exception e)
e.printStackTrace();
Log.e("My Networking", "Oh no, error occurred " + e.toString());
return null;
private static String readStream(InputStream is) throws IOException
final BufferedReader reader = new BufferedReader(new InputStreamReader(is, Charset.forName("US-ASCII")));
StringBuilder total = new StringBuilder();
String line;
while ((line = reader.readLine()) != null)
total.append(line);
if (reader != null)
reader.close();
return total.toString();
例如
new MyHttpRequestTask().execute(myUrl);
另外,记得将 build.gradle 中的 minSdkVersion
加到 16
minSdkVersion 16
【讨论】:
【参考方案7】:在android中添加play-services-safetynet
库build.gradle
:
implementation 'com.google.android.gms:play-services-safetynet:+'
并将此代码添加到您的MainApplication.java
:
@Override
public void onCreate()
super.onCreate();
upgradeSecurityProvider();
SoLoader.init(this, /* native exopackage */ false);
private void upgradeSecurityProvider()
ProviderInstaller.installIfNeededAsync(this, new ProviderInstallListener()
@Override
public void onProviderInstalled()
@Override
public void onProviderInstallFailed(int errorCode, Intent recoveryIntent)
// GooglePlayServicesUtil.showErrorNotification(errorCode, MainApplication.this);
GoogleApiAvailability.getInstance().showErrorNotification(MainApplication.this, errorCode);
);
