Android gets the current hidden and hidden WiFi encryption Method (security)

1. There are several ways of general WiFi encryption:(1). WPA-PSK/WPA2-PSK (Currently the safest home encryption)
(2). WPA/WPA2 (Less secure)
(3). WEP (poor security)

2. General Click System the current network will have pop-up details
So thisSecurityHow did you get it? By looking at the system source code know:

public class Mainactivity extends Activity {@Override protected void onCreate (Bundle savedinstancestate) {s        Uper.oncreate (savedinstancestate);        Setcontentview (R.layout.activity_main);        Wifimanager Mwifimanager = (wifimanager) getsystemservice (Context.wifi_service);        Wifiinfo info = Mwifimanager.getconnectioninfo ();        Get the configured network connection list<wificonfiguration> wificonfiglist = Mwifimanager.getconfigurednetworks ();            for (int i = 0; i < wificonfiglist.size (); i++) {log.i ("Hefeng", Wificonfiglist.get (i). toString ()); LOG.I ("Hefeng", Info.getssid () + "| |" + wificonfiglist.get (i).            SSID); if (Info.getssid (). Equals (Wificonfiglist.get (i).            SSID) {log.e ("Hefeng", "Current network security:" + getsecurity (Wificonfiglist.get (i))); }}}/** * These values is matched in string arrays--changes must is kept in sync */static fi    nal int security_none = 0; static final int SecuritY_WEP = 1;    static final int SECURITY_PSK = 2;    static final int security_eap = 3;            static int getsecurity (wificonfiguration config) {if (Config.allowedKeyManagement.get (KEYMGMT.WPA_PSK)) {        return SECURITY_PSK;            } if (Config.allowedKeyManagement.get (keymgmt.wpa_eap) | | config.allowedKeyManagement.get (keymgmt.ieee8021x)) {        return security_eap; } return (config.wepkeys[0]! = null)?    Security_wep:security_none; }

So you can get it. Doing so will prevent your wifi SSID from being hidden and can also get to encryption Mode 3. General access to encryption is the case, but once you set the SSID on the router to hide, you will not be able to search

public void Getciphertype (context context, String SSID) {        Wifimanager Wifimanager = (Wifimanager) Context.getsystemservice (context.wifi_service);        list<scanresult> list = Wifimanager.getscanresults ();        for (Scanresult scresult:list) {            if (! Textutils.isempty (SCRESULT.SSID) && scResult.SSID.equals (SSID)) {                String capabilities = scresult.capabilities;                LOG.I ("Hefeng", "capabilities=" + capabilities);                if (! Textutils.isempty (capabilities)) {                    if (Capabilities.contains ("WPA") | | capabilities.contains ("WPA")) {                        LOG.I ("Hefeng", "WPA");                    else if (Capabilities.contains ("WEP") | | capabilities.contains ("WEP")) {                        log.i ("Hefeng", "WEP");                    } else {                        log.i ("Hefeng", "No");}}}}
