如何在iOS / iPhone / iPad上获得WiFi加密模式？
如何在没有私有库的情况下在iOS中获得Wi-Fi加密模式？
以上答案中的代码最初发布在本网站上： http ： //www.codeproject.com/Articles/621213/Non-Standard-Way-to-Get-Inaccessible-Data-from-iOS
顺便说一下， #include 这段代码工作，你需要在#include 包含适当的头文件，这样你的编译器NDR_record_t ndr识别NDR_record_t ndr 。
但是，这整个设置实际上并没有返回当前WiFi的加密模式，而是AirPort的配置（上面代码中的变量key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AirPort，这是我在Mac终端中运行$scutil获得的（例如Setup:/Network/Interface/en0/IPv4或Setup:/Network/Interface/en0/Modem或者来自这个网站 ）
希望能帮助有类似问题的人……
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" -(NSDictionary *)getSCdata:(NSString *)key { if(SYSTEM_VERSION_LESS_THAN(@"6.0")) { // It does not work on iOS 5.* return nil; } struct send_body {mach_msg_header_t header; int count; UInt8 *addr; CFIndex size0; int flags; NDR_record_t ndr; CFIndex size; int retB; int rcB; int f24; int f28;}; mach_port_t bootstrapport = MACH_PORT_NULL; mach_port_t configport = MACH_PORT_NULL; mach_msg_header_t *msg; mach_msg_return_t msg_return; struct send_body send_msg; // Make request CFDataRef extRepr; extRepr = CFStringCreateExternalRepresentation(NULL, (__bridge CFStringRef)(key), kCFStringEncodingUTF8, 0); // Connect to Mach MIG port of configd task_get_bootstrap_port(mach_task_self(), &bootstrapport); bootstrap_look_up2(bootstrapport, kMachPortConfigd, &configport, 0, 8LL); // Make request send_msg.count = 1; send_msg.addr = (UInt8*)CFDataGetBytePtr(extRepr); send_msg.size0 = CFDataGetLength(extRepr); send_msg.size = CFDataGetLength(extRepr); send_msg.flags = 0x1000100u; send_msg.ndr = NDR_record; // Make message header msg = &(send_msg.header); msg->msgh_bits = 0x80001513u; msg->msgh_remote_port = configport; msg->msgh_local_port = mig_get_reply_port(); msg->msgh_id = 20010; // Request server msg_return = mach_msg(msg, 3, 0x34u, 0x44u, msg->msgh_local_port, 0, 0); if(msg_return) { 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); } } else if ( msg->msgh_id != 71 && msg->msgh_id == 20110 && msg->msgh_bits <= -1 ) { if ((send_msg.flags & 0xFF000000) == 0x1000000) { CFDataRef deserializedData = CFDataCreateWithBytesNoCopy(kCFAllocatorDefault, send_msg.addr,send_msg.size0, kCFAllocatorNull); CFPropertyListRef proplist = CFPropertyListCreateWithData(kCFAllocatorDefault, deserializedData, kCFPropertyListImmutable, NULL, NULL); mig_dealloc_reply_port(msg->msgh_local_port); 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); CFRelease(deserializedData); CFRelease(extRepr); return property_list; } } mig_dealloc_reply_port(msg->msgh_local_port); mach_port_deallocate(mach_task_self(), bootstrapport); mach_port_deallocate(mach_task_self(), configport); mach_msg_destroy(msg); CFRelease(extRepr); return nil; }
