This keygenme deals with Permutations, coded in C/ASM.
I coded this one on a sunday afternoon, just after found my
old Rubik's Cube 5*5*5 hidden under my bed... and I had an idea !
I also wrote a keygen for this keygenme without any brute forcing (due to the complexity).
Then do not use brute force to write your own one too.
If you find a correct key I owe you a beer

You can submit solution to crackmes.de.
You can contact me on #uct @ Epiknet.
You can try to send me a travler pidgin over the sea, but it's not sure.

There is no packing protection, or any anti-debugger...
if a debugger is detected, the XM (Music) is not launched.

30. Oct 2008		Hehe, I actually had the same idea some months ago, but was too lazy to look up Rubik's Cube formulae.

ratsoul had a rubik's cube keygenme in Oct 2007:

__imp__'s solution is very good, maybe he will see this one too

30. Oct 2008		@andrewl.us: Indeed, I didn't saw this one... it seems to be the same concept, except the complexity... 0x3D * 0x3D * 0x3D or 0x3 * 0x3 * 0x3 is the same solving method, so this is not a problem cause you can reduce the environnement. Anyway, my algorithm is not reproducing the rubik's cube physics, but it's close.
jE!
