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
|
|
|
