This one is interesting. I was able to crack it and I am working on patching it/key gen. Here is a sample:

fishing is easy for this one, but keygening need some time :)

The keygen isn't that hard, the hard part is to patch, which is almost impossible since it is packed. I can patch the binary in memory every time. To create the keygen I will just use inline assembly.

I have submitted a patch, which I thought was more challenging from the comment about patching. I completely understand how the keys are generated and I will have a working keygen working tomorrow.

Can I unpack it and them patch the unpacked file?

How would you patch a packed binary? I am curious. Please explain, as I don't want to be boring. Generating the key, that is boring. :-)
