We all thank to DStuff for his great work l2encdec.
Since NC updated LineageII to Chapter2 EP1,obviously ,they did not want us do much thing about l2.exe.Themdia seems a nice keeper dog.In china,TMD stands for Themdia,and the other meaning of TMD is "-beep-".Thanks for Themdia,NO key found in l2.exe-patcher says.
I found a way to replace l2encdec’s RSA key in to l2.exe of Chinese Mainland version,but seems the encryption was different for NA version.With help at l2wh’s forum,I got NA l2.exe with the whole system directory.Finally the patch was done.
Here it is:

ONLY FOR CURRENT VERSION! If NC updated l2.exe then it needs a re-patching.
The rar only contains patched l2.exe,so you need to patch other files in system dir by yourself.
Just do a full check to recover orginal l2.exe.
