Yannick,
You'll want to peruse Fravia's web site on reverse engineering (and other 
things) http://www.woodmann.com/fravia/protec.htm. That specific page 
covers just your concerns.

Hi, 
   I am wondering if there are any techniques to make a CD-Key of the like 

unbreakable.  Either by giving it a cancelation date and a periodic 
renewal 
from a server or just by using self md5 signature on the resulting 
executable.  I know it must not be easy because the whole software piracy 
problem would be resolved but there must be some way to make it really 
hard 
to break it.  Anyone have hints on this issue ?

Thanks
