Gmc:

If you use the search feature at the top of this page and enter "sentinel" as keyword, you will be pleased with the results. There has been much discussion over the sentinel protections. Also, take a look at the crackme we did a project on (CyberHeg's). There is much information to aid in your learning adventure at this site. Once you have read as much as you feel you need, try it out, and describe what you did and what happened as a result so we may further assist you and so others may learn as well. Just remember to use generic code as examples rather than straight rips that reveal commercial software identities (at least when using public forums).
