How to write your own .net obfuscator

Question

I am very curious as to how people write their own obfuscator.

How hard would it be to simply do the following:

1. rename all public methods with GUID type names.

Where would I start? How would I go about reading the .net dll assemby, pulling the public methods out and renaming them?

Answer 1

You can check those two projects that are using Cecil to write an open-source obfuscator:

• http://code.google.com/p/obfuscar/
• http://www.codeplex.com/SharpObfuscator
