it's funny, in my opinion the difficult is try to understand how this crackme checks the key's length ...

I didn't reverse the keygen algorithm but patched to accept any input as valid. Should I still write a solution? It could be nice to illustrate the Windows Message event driven model of programming.

@sp4d3r: you can explain it in here or elsewhere given the link, for us to learn.
Thanks man!

Sounds solid. I'll write it up and post it. It was a fun challenge. I am still wrapping my head around the Floating Point instruction sets for x86 processors but sometimes less is more. :)

PLS somebody decrypt me the activation codes, keygen,, full access (functions are key-depends) of "neoSys" software.
Contact me at
I bought the activation code, but isn't work, and no answer for my contacts.

@kipkop: if you are the author of the app, l think it will be better for you to extract the protection routine, convert it to a keygenme or crackme and upload it as a challenge.

You may leave your comment, thoughts and discuss this crackme with other reversers here.
