Wie programmiere und lese ich WEP / EAP WiFi-Konfigurationen in Android?

Programmgesteuertes Erstellen und Lesen von WEP/EAP WiFi configurations in Android?

Ich habe eine Reihe von Leuten gesehen, die sich in verschiedenen Foren und in der ganzen Community mit dieser Frage auseinandergesetzt haben. Ich weiß, das ist nicht so einfach (besonders EAP) herauszufinden, denn als ich das Gleiche erreichen wollte, hatte ich auch einiges zu kämpfen. Nun, all die harte Arbeit der Code-Analyse und der Suche nach verschiedenen Implementierungen im Internet war für mich erledigt endlich in der lage das ziel zu erreichen. Der gesamte Kredit geht an die Anzahl der Open Source-Projekte und deren Entwickler.

Ich möchte dieses Wissen mit allen teilen, denn SO ermutigt das: "Es ist auch vollkommen in Ordnung, Ihre eigene Frage zu stellen und zu beantworten, solange Sie so tun, als ob Sie dies tun sind auf Gefahr: formulieren Sie es in Form einer Frage. "

Teil 1: Programmgesteuertes Erstellen einer WEP-WLAN-Konfiguration

Dies ist ziemlich einfach, WifiConfiguration macht die Schnittstelle verfügbar, um dieselbe zu erstellen. Hier ist der Beispielcode:

void saveWepConfig()
{
    WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
    WifiConfiguration wc = new WifiConfiguration(); 
    wc.SSID = "\"SSID_NAME\""; //IMP! This should be in Quotes!!
    wc.hiddenSSID = true;
    wc.status = WifiConfiguration.Status.DISABLED;     
    wc.priority = 40;
    wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN); 
    wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);

    wc.wepKeys[0] = "\"aaabbb1234\""; //This is the WEP Password
    wc.wepTxKeyIndex = 0;

    WifiManager  wifiManag = (WifiManager) this.getSystemService(WIFI_SERVICE);
    boolean res1 = wifiManag.setWifiEnabled(true);
    int res = wifi.addNetwork(wc);
    Log.d("WifiPreference", "add Network returned " + res );
    boolean es = wifi.saveConfiguration();
    Log.d("WifiPreference", "saveConfiguration returned " + es );
    boolean b = wifi.enableNetwork(res, true);   
    Log.d("WifiPreference", "enableNetwork returned " + b );  

}

Teil 2: Programmgesteuertes Lesen einer WEP-WLAN-Konfiguration
Wieder geradeaus. Hier ist der Beispielcode:

    void readWepConfig()
    { 
        WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
        List<WifiConfiguration> item = wifi.getConfiguredNetworks();
        int i = item.size();
        Log.d("WifiPreference", "NO OF CONFIG " + i );
        Iterator<WifiConfiguration> iter =  item.iterator();
        WifiConfiguration config = item.get(0);
        Log.d("WifiPreference", "SSID" + config.SSID);
        Log.d("WifiPreference", "PASSWORD" + config.preSharedKey);
        Log.d("WifiPreference", "ALLOWED ALGORITHMS");
        Log.d("WifiPreference", "LEAP" + config.allowedAuthAlgorithms.get(AuthAlgorithm.LEAP));
        Log.d("WifiPreference", "OPEN" + config.allowedAuthAlgorithms.get(AuthAlgorithm.OPEN));
        Log.d("WifiPreference", "SHARED" + config.allowedAuthAlgorithms.get(AuthAlgorithm.SHARED));
        Log.d("WifiPreference", "GROUP CIPHERS");
        Log.d("WifiPreference", "CCMP" + config.allowedGroupCiphers.get(GroupCipher.CCMP));
        Log.d("WifiPreference", "TKIP" + config.allowedGroupCiphers.get(GroupCipher.TKIP));
        Log.d("WifiPreference", "WEP104" + config.allowedGroupCiphers.get(GroupCipher.WEP104));
        Log.d("WifiPreference", "WEP40" + config.allowedGroupCiphers.get(GroupCipher.WEP40));
        Log.d("WifiPreference", "KEYMGMT");
        Log.d("WifiPreference", "IEEE8021X" + config.allowedKeyManagement.get(KeyMgmt.IEEE8021X));
        Log.d("WifiPreference", "NONE" + config.allowedKeyManagement.get(KeyMgmt.NONE));
        Log.d("WifiPreference", "WPA_EAP" + config.allowedKeyManagement.get(KeyMgmt.WPA_EAP));
        Log.d("WifiPreference", "WPA_PSK" + config.allowedKeyManagement.get(KeyMgmt.WPA_PSK));
        Log.d("WifiPreference", "PairWiseCipher");
        Log.d("WifiPreference", "CCMP" + config.allowedPairwiseCiphers.get(PairwiseCipher.CCMP));
        Log.d("WifiPreference", "NONE" + config.allowedPairwiseCiphers.get(PairwiseCipher.NONE));
        Log.d("WifiPreference", "TKIP" + config.allowedPairwiseCiphers.get(PairwiseCipher.TKIP));
        Log.d("WifiPreference", "Protocols");
        Log.d("WifiPreference", "RSN" + config.allowedProtocols.get(Protocol.RSN));
        Log.d("WifiPreference", "WPA" + config.allowedProtocols.get(Protocol.WPA));
        Log.d("WifiPreference", "WEP Key Strings");
        String[] wepKeys = config.wepKeys;
        Log.d("WifiPreference", "WEP KEY 0" + wepKeys[0]);
        Log.d("WifiPreference", "WEP KEY 1" + wepKeys[1]);
        Log.d("WifiPreference", "WEP KEY 2" + wepKeys[2]);
        Log.d("WifiPreference", "WEP KEY 3" + wepKeys[3]);
    }

Teil 3: Programmgesteuertes Lesen einer EAP-WLAN-Konfiguration
Nun, das ist schwierig. Den Code zum Speichern einer EAP-WLAN-Konfiguration finden Sie in der Benutzeroberfläche von Vanilla Android unter WifiDialog.Java . Nun, einfach genug. Wir können den gleichen Code in unserer Anwendung verwenden. Nun, NEIN! Wenn Sie dies versuchen, erhalten Sie die Fehlermeldung, dass die Symbole eap, phase, client_cert Und so weiter nicht gefunden werden können. Eine kleine detaillierte Untersuchung zeigt uns EnterpriseFieldis private Innerhalb der Klasse WiFiConfiguration und alle Symbole, die wir nicht finden können, sind vom Typ EnterpriseField. Nun, wir haben eine Straßensperre erreicht. Wir benötigen diese Felder zum Lesen/Speichern einer EAP-Konfiguration, haben aber keinen programmgesteuerten Zugriff darauf!

Java Reflection API Zur RettungNun, ich bin kein Java Experte, also werde ich es nicht tun Erfahren Sie mehr über die Reflection-API als solche, und Sie können bei Google nach Tutorials suchen oder weitere Informationen erhalten hier . Um es kurz und bündig zu halten, können Sie mit Reflection API zur Laufzeit Klassen, Interfaces, Felder und Methoden untersuchen, ohne die Namen der Klassen, Methoden usw. beim Kompilieren zu kennen. Es ist auch möglich, neue Objekte zu instanziieren, Methoden aufzurufen und Feldwerte mithilfe von Reflection abzurufen/festzulegen. Wichtig: Reflection kann Ihnen den Zugriff auf private Datenelemente in einer Klasse erleichtern.Nun, das ist es, was wir brauchen, nicht wahr? :)

Schauen wir uns nun das Codebeispiel an, in dem gezeigt wird, wie eine EAP WiFi-Konfiguration mit Reflection Api gelesen wird. Als Bonus protokolliert das Snippet die Konfiguration in eine Datei und speichert sie auf der SD-Karte. Ziemlich flott. Äh. Ein kleiner Überblick über Reflection Api und ich bin sicher, dass es einfach ist, den folgenden Code zu verstehen.

    private static final String INT_PRIVATE_KEY = "private_key";
    private static final String INT_PHASE2 = "phase2";
    private static final String INT_PASSWORD = "password";
    private static final String INT_IDENTITY = "identity";
    private static final String INT_EAP = "eap";
    private static final String INT_CLIENT_CERT = "client_cert";
    private static final String INT_CA_CERT = "ca_cert";
    private static final String INT_ANONYMOUS_IDENTITY = "anonymous_identity";
    final String INT_ENTERPRISEFIELD_NAME = "Android.net.wifi.WifiConfiguration$EnterpriseField";

Dies ist der Code zum Erstellen einer Protokolldatei auf der SD-Karte, bevor die Funktion readEapConfig() aufgerufen wird.

        BufferedWriter out = null;
        try 
        {
            File root = Environment.getExternalStorageDirectory();
            Toast toast = Toast.makeText(this, "SD CARD mounted and writable? " + root.canWrite(), 5000);
            toast.show();
            if (root.canWrite())
            {
                File gpxfile = new File(root, "ReadConfigLog.txt");
                FileWriter gpxwriter = new FileWriter(gpxfile);
                out = new BufferedWriter(gpxwriter);
                out.write("Hello world");
                //out.close();
            }
        } catch (IOException e) 
        {
            Toast toast = Toast.makeText(this, "Problem reading SD CARD", 3000);
            Toast toast2 = Toast.makeText(this, "Please take logs using Logcat", 5000);
            Log.e("<<<<<<<<<<WifiPreference>>>>>>>>>>>>", "Could not write file " + e.getMessage());
        }

Nun ist die readEapConfig() -Funktion selbst:

    void readEapConfig(BufferedWriter out)
    {
        /*Get the WifiService */        
        WifiManager wifi = (WifiManager)getSystemService(WIFI_SERVICE);
        /*Get All WIfi configurations*/
        List<WifiConfiguration> configList = wifi.getConfiguredNetworks();
        /*Now we need to search appropriate configuration i.e. with name SSID_Name*/
        for(int i = 0;i<configList.size();i++)
        {
            if(configList.get(i).SSID.contentEquals("\"SSID_NAME\""))
            {
                /*We found the appropriate config now read all config details*/
                Iterator<WifiConfiguration> iter =  configList.iterator();
                WifiConfiguration config = configList.get(i);

                /*I dont think these fields have anything to do with EAP config but still will
                 * print these to be on safe side*/
                try {
                Log.d("<<<<<<<<<<WifiPreference>>>>>>>>>>>>", "[SSID]" + config.SSID);

Das war's! Und ich hoffe, das hilft einem verlorenen Entwickler, irgendwo, irgendwann :)

Android hat eine API zu JellyBean 4.3 hinzugefügt. Sie müssen diese Option verwenden, wenn Sie WIFI in API 18 konfigurieren möchten:

Hoffe das hilft jemandem. @Android-Lerner Ich habe die Informationen zu AdHocFrequency und SSID entfernt, da sie Abstürze verursachten, aber meine Ergebnisse waren ohne sie immer noch gut.

Die WEP-Schlüssel sind maskiert, so dass sie mit dem genannten Code nicht gelesen werden können

    Log.d("WifiPreference", "WEP KEY 0" + wepKeys[0]);
    Log.d("WifiPreference", "WEP KEY 1" + wepKeys[1]);
    Log.d("WifiPreference", "WEP KEY 2" + wepKeys[2]);
    Log.d("WifiPreference", "WEP KEY 3" + wepKeys[3]);

Gibt es eine Möglichkeit, dies auf dieselbe Weise zu lösen wie die EAP-Lösung? Mit Reflektion?
