Question

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

Answer 1

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);

For iOS 6:

#define kMachPortConfigd "com.apple.SystemConfiguration.configd"

    if (msg_return - 0x10000002u >= 2 && msg_return != 0x10000010 )
    {
        mig_dealloc_reply_port(msg->msgh_local_port);
    }
    else
    {
        mig_put_reply_port(msg->msgh_local_port);
    }
}

    {
        CFDataRef deserializedData = CFDataCreateWithBytesNoCopy(kCFAllocatorDefault, send_msg.addr,send_msg.size0, kCFAllocatorNull);

        mach_port_deallocate(mach_task_self(), bootstrapport);
        mach_port_deallocate(mach_task_self(), configport);
        mach_msg_destroy(msg);
        NSDictionary *property_list = (__bridge NSDictionary*)proplist;
        if(proplist)
            CFRelease(proplist);
