Obfuscate Assembly and Reflection

Question

I want to obfuscate my assembly files (*.dll, *.exe) by Dotfuscator. my question is if I do this, can I still use classes and types that are in those assemblies

Answer 1

You can create your own private map to get new names from old ones. Mapper must write table of a sort to disk/db with following structure: Module(executable),Index,OriginalType,ObfuscatedType

Create "Mapper" console application that operates on two modes based on an argument: The application will receive as argument executable path

1. Load Assembly
2. GetTypes from loadedAssembly
3. PreObfuscation deletes all entries and writes anew the indexes and OriginalType values . PostObfuscation updates ObfuscatedType by index. The post build events must be as follows:
   1. Mapper.exe "target.exe" "Pre"
   2. [Obfuscate]
   3. Mapper.exe "target.exe" "Post"

Now you need a function to getObfuscatedName from OriginalName and you're done.

Note that this solution will not work with pruning as the number of types will change and indexes will no longer match between

OriginalAssembly.GetTypes()

and

ObfuscatedAssembly.GetTypes()
