If it encounters an unknown SSL certificate, it asks the -user whether to accept the certificate once, permanently or to abort the -connection. This is a step in preventing man-in-the-middle attacks by blindly -accepting any invalid, self-signed and/or expired certificates. - -MTM is aimed at providing seamless integration into your Android application, -and the source code is available under the MIT license. - -## Screenshots - - - - - -## Status - -MemorizingTrustManager is in production use in the -[yaxim XMPP client](https://yaxim.org/). It is usable and easy to integrate, -though it does not yet support hostname validation (the Java API makes it -**hard** to integrate). - -## Integration - -MTM is easy to integrate into your own application. Follow these steps or have -a look into the demo application in the `example` directory. - -### 1. Add MTM to your project - -Download the MTM source from GitHub, or add it as a -[git submodule](http://git-scm.com/docs/git-submodule): - - # plain download: - git clone https://github.com/ge0rg/MemorizingTrustManager - # submodule: - git submodule add https://github.com/ge0rg/MemorizingTrustManager - -Then add a library project dependency to `default.properties`: - - android.library.reference.1=MemorizingTrustManager - -### 2. Add the MTM (popup) Activity to your manifest - -Edit your `AndroidManifest.xml` and add the MTM activity element right before the -end of your closing `</application>` tag. - - ... - <activity android:name="de.duenndns.ssl.MemorizingActivity" - android:theme="@android:style/Theme.Translucent.NoTitleBar" - /> - </application> - </manifest> - -### 3. Hook MTM as the default TrustManager for your connection type - -Hooking MemorizingTrustmanager in HTTPS connections: - - // register MemorizingTrustManager for HTTPS - SSLContext sc = SSLContext.getInstance("TLS"); - MemorizingTrustManager mtm = new MemorizingTrustManager(this); - sc.init(null, new X509TrustManager[] { mtm }, new java.security.SecureRandom()); - HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); - HttpsURLConnection.setDefaultHostnameVerifier( - mtm.wrapHostnameVerifier(HttpsURLConnection.getDefaultHostnameVerifier())); - - -Or, for aSmack you can use `setCustomSSLContext()`: - - org.jivesoftware.smack.ConnectionConfiguration connectionConfiguration = … - SSLContext sc = SSLContext.getInstance("TLS"); - MemorizingTrustManager mtm = new MemorizingTrustManager(this); - sc.init(null, new X509TrustManager[] { mtm }, new java.security.SecureRandom()); - connectionConfiguration.setCustomSSLContext(sc); - connectionConfiguration.setHostnameVerifier( - mtm.wrapHostnameVerifier(new org.apache.http.conn.ssl.StrictHostnameVerifier())); - -By default, MTM falls back to the system `TrustManager` before asking the user. -If you do not trust the establishment, you can enforce a dialog on *every new -connection* by supplying a `defaultTrustManager = null` parameter to the -constructor: - - MemorizingTrustManager mtm = new MemorizingTrustManager(this, null); - -If you want to use a different underlying `TrustManager`, like -[AndroidPinning](https://github.com/moxie0/AndroidPinning), just supply that to -MTM's constructor: - - X509TrustManager pinning = new PinningTrustManager(SystemKeyStore.getInstance(), - new String[] {"f30012bbc18c231ac1a44b788e410ce754182513"}, 0); - MemorizingTrustManager mtm = new MemorizingTrustManager(this, pinning); - -### 4. Profit! - -### Logging - -MTM uses java.util.logging (JUL) for logging purposes. If you have not -configured a Handler for JUL, then Android will by default log all -messages of Level.INFO or higher. In order to get also the debug log -messages (those with Level.FINE or lower) you need to configure a -Handler accordingly. The MTM example project contains -de.duenndns.mtmexample.JULHandler, which allows to enable and disable -debug logging at runtime. - -## Alternatives - -MemorizingTrustManager is not the only one out there. - -[**NetCipher**](https://guardianproject.info/code/netcipher/) is an Android -library made by the [Guardian Project](https://guardianproject.info/) to -improve network security for mobile apps. It comes with a StrongTrustManager -to do more thorough certificate checks, an independent Root CA store, and code -to easily route your traffic through -[the Tor network](https://www.torproject.org/) using [Orbot](https://guardianproject.info/apps/orbot/). - -[**AndroidPinning**](https://github.com/moxie0/AndroidPinning) is another Android -library, written by [Moxie Marlinspike](http://www.thoughtcrime.org/) to allow -pinning of server certificates, improving security against government-scale -MitM attacks.
