software protections help

thank you for your answers ! i am newbie and i dont know how to start .i think that tutorials does not help me because i dont understand the assembly .if i was buy a book about how to learn assembly this will make the things easier ?

I might be wrong, but I thin it's a bit too early for you to buy an assembler book. Try to search for good tutorials which explain also the background WHY you are patching something or WHY you should look at adress xxyyzz for a serial. If you found such a tutorial, try to find a nice Assembler reference on the net.

would be a good start. This will save you some money for now and still teaches you some stuff.

This ebook is good for beginners Hacker Disassembling Uncovered ... i forgot the site . so i attached (roughly large attachment >4mb ) it here. Theres another one worth mentioning although i haven't read it yet.

Exploiting Software: How To Break Code
by Greg Hoglund, Gary McGraw

i can't find ebook version of this book if somebody knows where, pls share it.

Annyone red Lord Hrun's cracking tutorial? Sounds to be a good one, but haven't tracked it down yet.

see daemon.anticrack.de, but always to protect better u have to know whats in revese is goin on try to make some connections with crc and working of you app, for example when some calculation depends on crc its very hard to find this and make REAL working, calculation's ( for example ) may depens on serial number etc itr tricky coz app may looks like working but its not working

Well, I recently stumbled accross this page which has some excellent anti cracking FAQ, especially if you are programming in Delphi
