Re: Breaking .NET Compact Framework code - how easy is it

I think what Ginny is saying is put the algorithm in the C++ unmanaged
module, if this call fails (commented out whatever) then the calling C#
managed code will also fail if coded correctly.

Another thing if generating a licence number not to return true or false
from the algorithm as this makes your software easier to break. Instead,
return the correct licence number then do a comparison within the C# maybe
byte by byte, or even bit by bit to make it more difficult to crack. You
could even perform some unnecessary processing during this comparison stage
to confuse the cracker.

Other people might have other tips to make the cracking process more
difficult...

Bearing in mind 33% of software today is pirate software, this issue never
gets enough attention!

Cheers
Simon.
