Fatal Error: Reverse Mangler Clash #21

Open lukaspetrik opened 5 years ago

lukaspetrik commented 5 years ago

When using caesar mode, MachObfuscator crashes:

Fatal error: ReverseMangler clashed on symbol 'A': file /Users/lukas/Downloads/MachObfuscator-master/MachObfuscator/SymbolMangling/CaesarMangler/CaesarMangler.swift, line 30

./BuildPhases/obfuscation: line 30: 9155 Illegal instruction: 4 MachObfuscator -v -m caesar //Users/lukas/Library/Developer/Xcode/DerivedData/Wakanda-fuikddtnfvllirgvhznhqqfaeofh/Build/Products/Debug-iphoneos/{REMOVED}.app

Using XCode 10.2.1 and the newest sources of MachObfuscator from master branch. realWords mode works fine.

Thanks for reporting this issue. Caesar mangler was initially created for debug, when the project was born. It is very easy to demangle, so I would not recommend using this on production. I think I will remove Caesar mangler from MachObfuscator. I also have some ideas for other manglers (Chinese mangler, external dictionary mangler, etc.).
