Thanks, do you have any hints or advice to find cryptographic subroutines? Sorry for asking but i am novice when it comes to cryptography? But i ll learn certainly.

To find cryptographic subroutines per se, the CC tool found in this thread is excellent.

You can find a MEGA download link in the last post there.

The above tool will help if you want to quickly scan for any cryptographic routines in the code.

However if the crypto is a part of the dongle protection code itself, then, while this tool can discover the crypto, it's not that easy to solve it without having a good knowledge of that dongle's protection itself (from the SDK, among other things, for example)

Thanks for cc. I am using it now.

I analysed the loaded modules. I think these are crypto related ones.
cryptsp.dll, rsaenh.dll, EvCrypt.dll and enhkey.dll

EvCrypt.dll is from www.cryptsoft.com and enhkey.dll is for hasp dongle.
I am trying to understand role of EvCrypt.dll. Any hints?

Cryptosoft ?

Well theres's a wealth of info on their page

You may want to go through the various datasheets to get a preliminary idea as to what features could have been used in your target.

Don't forget the "Additional Resources" section at the end. Contains a lot of useful info reg what's available in their software.

By the way, this sort of a thread should be opened in the "Dongle" sub-section and not in the "General Discussion" section of the forum which is visible to everyone on the internet.

Maybe the mods could move this thread over ?
