Rockey4ND info needed
 

This may sound silly and I may never even finish it but...

I am trying to write firmware for a microcontroller which will work as a Rockey4ND. So far, I have it enumerating properly and the find function partially works.

The problem is that I don't have a real rockey so I cannot look to see what is going to/from the device. Right now, what I could use is any information on what the device shows up as (the USB descriptor).

In the find function (more specifically, the Login routine), there is a MapViewOfFile call which uses the filename "Rockey4NDxxxxxxxx" (X is hardware ID returned from rockey. It then sets a flag in the mapping and unmaps it.

I think this is a login flag so that the particular dongle will no longer respond to find requests until it is logged out.

I would really like to know what the USB Descriptor details of a Rockey4ND are!

Anyone have one they could sniff around on for me?

Thanks,
psycho

By the way, this is more for learning than anything else. Don't have a program that is protected with it...

anyone got more information about rockey4nd?

Regards,

more...
1. hardware algo is recovered to source
2. all sweet in the user algo - if developer is not lazy =)

Go to www.pediy.com search clone tools. can modifly password and HID.

post these tools here. maybe someone else need them

rockey4 change password in Chinese version

This is for Rockey4 ( Firmware revision < 3.0 )
Not for Rockey4ND

Rockey4ND is almost totally dead dongle, it have some backdoor and leaked due to the JB8 chip been reversed. But if the devoloper use user-define algo well, it still have little bit good protection.
Enjoy it, just for fun.

Writes new passwords to Rockey4ND, but doesn't read available passwords.
good for cloning ...

Guide
 

any one emulate this dongle, guide her please

Hardware clone is much more stable than emulate it if you are just want to use your software. But the emulator is possible with bus level or by hid.dll method. Try to analysis the protocal, it's simpy xor algo and you can handle it easy. But the seed algo still can't publiced so table based should be current solution.

@ngoksun how to analysis the protocol any special tool is there

USBTrace is enough.

most chinese dongle had been cloned

sure,anyone can upload microdog hard clone tools pls.

@ngoksun, @fox - any hints about seed algo?
