What I've sad is especially true for limited-market, not so popular applications! If opening up your exe file with notepad provides the name of the "protection schema" readily available, any Jon Doe user would be able to crack your application using google! No more disassembling and no more real cracking. Just plain matching your application's security method to a list of known commercial "protection schemas"! Who knows, maybe next year a script kiddie with too much free time will write a "security" application that would make identifying the "commercial grade" protection schema a snap!
If on the other hand you're interesting in keeping and improving your own protection schema, just come up with specific questions. I'm sure lots of us will follow the discussions. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:delphi-talk- > [EMAIL PROTECTED] On Behalf Of Human > Sent: Monday, April 03, 2006 4:50 PM > To: Delphi-Talk Discussion List > Subject: RE: What VCL do you use for protecting your application? > > Thanks allot for your indications. > I already looked on cracking forums and web sites and the conclusions are > pretty 'dark'. > Those guys can crack anything.
