Description

I coded this app in 2007 and gave it a pro to protect it against reverse engineering and bypassing the login system. Since I don't have the original source code anymore, I'm curious about solutions to see my old application again. Hints: - The underlying application is written in C# - The pro has apparently packed it into a Delphi application - PATCHING is explicitly allowed (if the login system is bypassed, a big form opens) - Bonus point for: Extract the embedded C# program (.NET executable or DLL)

Keller on 2019-04-21 20:29: Phemis, thank you for your participation. I deobfuscated the file you unpacked and it is the "ezencryption_lib.exe", part of the .NET obfuscator "Eziriz.NET Reactor". Now we know which obfuscator was used here back in 2007. However, this packed file does not seem to contain the actual program, only stuff related to the obfuscator.
