USB memroy flash AS dongle

and if it logical ot not..
if i have memroy flash can i use it as dongle..
explain more: ok
program.exe (i add shell to read the memroy serial number or somthing unique on it )
thanks

It is just a flash device so you could store some of your code or files and have the program look for them on the usb key. The problem is anyone could duplicate it just by copying the key.

It might be possible to find a specific brand of USB key that has a unique attribute that you could query for using WMI or some Win32. I can imagine that it would be very easy to bypass this protection though so I do not imagine it to be very effective.

Good idea
 

but you need a method to protect your files in USB, the best way is developing a new encrypt file system , and you need write a driver for it.

only i have many USB memroy flash. and interest to make from them .. a good dongles :)

as u said.. easy to bypass ..but for profesionall.don't forget ..all dongle we can bypass :)
but it is levels

Hi Guys,

If I look at my USB memory stick in my registry

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_Kalliba&Prod_Velocity&Rev_2.00\454542009DA80061&0

However there is no serial number there..

If you send raw packets to a USB device using a createfile handle pointing to the right USB root, USB hub and finally USB device you can populate this this structure (Find on MSDN):

typedef struct _USB_DEVICE_DESCRIPTOR {
UCHAR bLength ;
UCHAR bDescriptorType ;
USHORT bcdUSB ;
UCHAR bDeviceClass ;
UCHAR bDeviceSubClass ;
UCHAR bDeviceProtocol ;
UCHAR bMaxPacketSize0 ;
USHORT idVendor ;
USHORT idProduct ;
USHORT bcdDevice ;
UCHAR iManufacturer ;
UCHAR iProduct ;
UCHAR iSerialNumber ;
UCHAR bNumConfigurations ;
} USB_DEVICE_DESCRIPTOR, *PUSB_DEVICE_DESCRIPTOR ;

Here is a practical example and detailed discussion of this

This is a dump from my Kalliba USB memory stick:
Port=8
DeviceAddress=1
ConnectionStatus=1
MaxPower=300
MajorVersion=2
MinorVersion=0
ProductID=8552
VendorID=3744
Manufacturer=USB
Product=Flash Disk
Serial=454542009DA80061

Whether the serial number is unique to this device or only unique to my machine is another thing.

This serial number is not even remotely close to the serial stamped on the side of the device!

Hope this helps!!

minawahib1, it seems that your idea has already been implemented. Look at http://www.nalpeiron.com/products/protector_flash.asp

hehe :)
my idea is logical and already there..but with money needed ;)
i am still wait a final solution of how to make this shell with normal USB flash memroy
thanks all

minawahib1, you had a good idea, but i think it may not available at this time.

this is not a good idea.
if you have anything with embedded development, you can get devices even cheaper than them.

USB flash that works as protection already exists in the market. Called "SmartPico" and its a combination of SmartKey + PicoDisk.

@etienne
good thinking..can you give ex. and how to make
like a network card protection (read the MAC addres(what ever now we can change the mac ;) ?

@minawahib1: it likes FlexLM or SentinelLM with some software protected as Maya

thanks asus for answer .i will try it..
is any one have sentinel Lm 7.2 or 7.3 or higher cracked..
send to me PM
thanks all

Here you should go to h>>p://www.woodmann.com/crackz/Flexlm.htm

i forget the main idea...;)
i searchf for hot to make the USB flash(which so cheap ) into a dongle
not a protector like sentinel lm or armaillo or execryptor
thanks asus
