LimeLM activation and Reverse Engineering in DelphiAnswered

Hello all,

I would like to discuss methods for increasing the difficulty of reverse engineering a Delphi program protected by LimeLM activation. While it is known that no programming technique can provide 100% immunity against reverse engineering, there are ways to make it more challenging. For instance, a cracker may locate and remove the line of code that terminates the application (e.g., Application.Terminate;). Alternatively, they might identify a critical boolean evaluation and modify it to bypass the checking logic. It would be helpful if you could provide an example of such a scenario.

I must commend LimeLM for its effective use of cryptographically signed activation keys. However, I'm curious about the logic employed to verify these keys.

Thank you in advance.

Sincerely,
