How to get WiFi encryption mode on iOS/iPhone/iPad?

How to get Wi-Fi encryption mode in iOS without private libraries?

回答1:

The code from the answer above has been posted originally on this website: http://www.codeproject.com/Articles/621213/Non-Standard-Way-to-Get-Inaccessible-Data-from-iOS

By the way, for this code to work you need to include the appropriate header files with #include <mach/mach.h> so that your compiler recognizes NDR_record_t ndr.

However, this whole setup did not actually return me the encryption mode of the current WiFi, but rather the configuration of AirPort (the variable key in the code from above needs to be set to NSString *key = @"Setup:/Network/Interface/en0/AirPort"; before). I tried different values instead of AirPort which I got from running $scutil in the Terminal of my Mac (such as Setup:/Network/Interface/en0/IPv4 or Setup:/Network/Interface/en0/Modem or from this website)

Hope that helps someone having similar issues...

For iOS 5:

    aslmsg asl, message;
    aslresponse searchResult;
    int i;
    const char *key, *val;
    NSMutableArray *result_dicts = [NSMutableArray array];

    asl = asl_new(ASL_TYPE_QUERY);
    if (!asl)
    {
        DDLogCError(@"Failed creating ASL query");
    }
    asl_set_query(asl, "Sender", "kernel", ASL_QUERY_OP_EQUAL);
    asl_set_query(asl, "Message", "AppleBCMWLAN Joined BSS:", ASL_QUERY_OP_PREFIX|ASL_QUERY_OP_EQUAL);
    searchResult = asl_search(NULL, asl);
    while (NULL != (message = aslresponse_next(searchResult)))
    {
        NSMutableDictionary *tmpDict = [NSMutableDictionary dictionary];

        for (i = 0; (NULL != (key = asl_key(message, i))); i++)
        {
            NSString *keyString = [NSString stringWithUTF8String:(char *)key];

            val = asl_get(message, key);

            NSString *string = [NSString stringWithUTF8String:val];
            [tmpDict setObject:string forKey:keyString];
        }
        [result_dicts addObject:tmpDict];
    }
    aslresponse_free(searchResult);
    asl_free(asl);

    {
        mig_dealloc_reply_port(msg->msgh_local_port);
    }
    else
    {
        mig_put_reply_port(msg->msgh_local_port);
    }
