I read some articles about protecting your application against cracking.
describe that :
<if you trial software must be available in 30 days only , then dont try to use a system date-time.
Better to use a date-time of some system files (system.dat or DAO , BOOTLOG.txt, autoexec.bat etc).
Also dont forget that additionally you can create the some own hidden file during installation and use a date-time of this file.>
But my question :
Which one (system.dat ,DAO, bootlog.txt , autoexec.bat ) has a better feature for uncracking?
How can work with these issues(system.dat,DAO,boot
Thanks a lot.
