1. Quick Intro
Hi folks, this is my second tutorial about ExeCryptor , altough I don't know will I publish it before one that I wrote first (for official ExeCryptor crackme). Target for this tutorial is diProtector v1.0 (google it). I don't know is it latest since I had it on my hard drive for a while. Target is compiled in MASM and it doesn't have stolen OEP or functions, plus there are very few imports in the file. All that makes unpacking much easier. Tools that I used for this job are OllyDbg 1.10, LordPE, ImpREC, some hex editor. You will not need any plugins or patches to hide Olly. We will do all manually.

SafeDisc 3.20 - 4.00
If you ever played games in your life, then you for sure know what is SafeDisc. SafeDisc is one of the today most used CD protections. In a previous tutorial we met SafeDisc "small brother" - SafeCast. SafeDisc is product of the same company and it is almost indentical as SafeCast. Main difference is that SafeDisc checks for bad sectors on the CD to be sure that program is running from original one. Bad sectors cannot be copied to another CD. Well it shouldn't be, but programs like Alcohol 120% and similar can do that. It also depends of SafeDisc version. I'm not quite sure about that, copying CDs doesn't interest me. Removing protection layer is objective of this tutorial. For this tutorial you need original CD and Windows XP.
What is SafeCast? Dou you know what is SafeDisc maybe? SafeDisc is well known CD protection from Macrovision, used in many software that comes on CD/DVD (games, etc...) . SafeCast is the same thing except it is made for programs that doesn't came on CD (downloadable programs, trial versions, etc...). In this tutorial we will see how version 2.4 can be unpacked. It is little older one, but I had program protected with it. Target for my tutorial is Adobe Photoshop 8.0, but this should be generic aproach for all 2.4 versions.
