[keygenme] Keygenme 18

[ChOoKi]

My last one for this year and it should be fun to reverse but you might wanna take your time with it.

 

Basic info:
Compiler: Borland Delphi
Packer: A walk in the park to unpack, and this time DO NOT ask GIV!
Level: Just right to keep you entertained
Solution: A keygen and maybe a tutorial to share your knowledge with othersEnjoy & Good Luck

Very easy to unpack.

No special features of protector used like checking if is packed, API redirection etc.

Just in case someone feels challenged by the packer (doubt it very much).

It didn't seem very interesting, appart from the need of coding a fast dlp-solving method (for instance Index Calculus).

The proper solution envolves the coding a dlp solving method?

Just a conceptualization of something that I have. I'd like to peak into the source code of the crackme (a request)

@xSRTsect: Solution accepted but I must decline your request (the source remains private)

Remark: I have just noticed that I may have screwed up by using operator >> for istream reading into strings. It will only read untill a empty space is found, it could be easily fixed using getline instead. So if testing the keygen you should not use names with spaces.
