Reverse engineered code of L2OFF server Chronicles-1
This code is published for STUDY PURPOSE ONLY. If you want use this code, you should contact NCSoft.
NOTE: branch "legacy" contains only ORIGINALY decompiled code, with origin bugs, MSVC2008 required to build it.
NOTE: All fixes and improvements are going to "develop" branch. MSVC2013 or higher is required to build it.
- generated/ - directory, which contains IDA (6.8) / Hex-Rays generated decompiled code, which is used as a reference to further creating of compilable code
- reversed/ - directory, which contains manualy fixed generated code - structure definitions, renamings, etc.
- src/ - directory, which contains manualy fixed compilable code
- install newest cmake
- go to the project's root directory
- run commands:
mkdir build
cd build
cmake ../
or to build with MSVC 2008:
cmake -G "Visual Studio 9 2008" ../
cmake --build .
cmake --build . --target install
- after that, you will have MSVC project inside build/ directory, and built ready-to-use L2AuthD inside build/install
- Reverse engineered code of L2AuthD.exe, build version: 40504
- All modules were originally decompiled, including Blowfish algorithm, MD5, original prints (including Korean), password encryptions (for DB access and user ones), packet handling, call-stack report during crash, mail server, INI-file reading, etc
- The ONLY foreign code is DES algorithm. I wasn't able to decompile it at 100%, so some other open-source implementation is used
- Orignal Blowfish key is used: 5F 3B 35 2E 5D 39 34 2D 33 31 3D 3D 2D 25 78 54 21 5E 5B 24. Note, that there are few packs with changed BF keys:
5F 3B 35 2E 5D 39 34 2D 33 31 3D 3D 2D 25 78 54 21 5E 5B 24
6E 63 73 6F 66 74 6C 69 6E 65 61 67 65 32 2E 63 6F 6D 20 20
5B 3B 27 2E 5D 39 34 2D 33 31 3D 3D 2D 25 26 40 21 5E 2B 5D
