 Forums >>  Debuggers  >>  generate hasp dump

Topic created on: April 19, 2012 12:56 CDT by dsl400 .

it sounds kinda stupid
right!

here`s the trick

a .net application is protected with hasp and i don`t have a dongle dump to emulate or a dongle to copy then emulate.


my idea is to create a dump by using the values that the application expects from the dongle and emulate it.

can anyone guide me ?

I failed to understand what exactly the problem you're facing.

do you have trouble reversing the application?

do you need the technical tools to emulate such a device?

the idea sounds valid and should work as long as there's no secret key used in the process in an intelligent way (i.e. PK signing/verification).
do note that there are however a lot of standard compliant dongles that are still, although using some sort of cryptography, can be trivially bypassed.

another (perhaps simpler yet not as interesting) approach could be to patch the application to bypass the dongle verification.

there're a lot of more info we could use to help you further. please try to elaborate on the problems you've encountered and the device you are planning to reverse.

reversing/bypassing dongles is always a fun task, have fun!
