ios - 如何在 iOS/iPhone/iPad 上获得 WiFi 加密模式？

Question

如何在没有私有库的情况下在 iOS 中获取 Wi-Fi 加密模式？

Answer 1

上述答案中的代码最初已发布在此网站上：http: //www.codeproject.com/Articles/621213/Non-Standard-Way-to-Get-Inaccessible-Data-from-iOS

顺便说一句，要使此代码正常工作，您需要包含适当的头文件，#include <mach/mach.h>以便编译器识别NDR_record_t ndr.

但是，整个设置实际上并没有返回我当前 WiFi 的加密模式，而是 AirPort 的配置（key上面代码中的变量需要设置为NSString *key = @"Setup:/Network/Interface/en0/AirPort";之前）。我尝试了不同的值，而不是我在 Mac 的终端中运行得到的 AirPort $scutil（例如Setup:/Network/Interface/en0/IPv4or Setup:/Network/Interface/en0/Modemor from this website）

希望对遇到类似问题的人有所帮助...

对于 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);

对于 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);
