I am trying to create a Keygen for the Challenge Jinku Crypto KeyGenMe but am having some difficulty.

I see how the program unpacks and creates a call table of Windows functions via LoadLibrary and GetProcAddress. I have identified the critical test instruction at 0x401A0D for validity but the program appears to call many subroutines between the GetDlgItemTextA and this test instruction. Walking through the code is quickly becoming a nightmare.

I have not found any solution to the challenge. Can any of the veterans share their insights or thought processes for this solution. I am currently using IDAPRO 5.0.

Any help/insights would be great.

Thanks.
