Codecepticon does not work when a solution has more than 1 project included. An example of this is the SharpDPAPI project which also includes SharpChrome. In order to obfuscate it, you will have to remove one or the other. Codecepticon will catch this and will prompt you for action (continue/exit).
Currently C# obfuscation only works with Roslyn v3.9.0, as there is a but which affects renaming namespaces/functions: dotnet/roslyn#58463
When this issue is resolved, Codecepticon and its documentation will be updated. Codecepticon will catch this and will prompt you for action (continue/exit).
Due to the nature and complexity of PowerShell scripts, obfuscation of large/complex scripts may or may not work.
Codecepticon cannot obfuscate an office document such as Word/Excel. You will have to obfuscate each *.bas file and then manually insert into your document.
