Hikari

Hikari is a port of Obfuscator-LLVM with a few custom built passes.

Source

Available at master branch

Install

For macOS,Download from Releases page,Extract Hikari.xctoolchain to ~/Library/Developer/. Note that I do not personally use Xcode as such I'm not able to help with issues regarding Xcode Intergration

For other platforms, compile and install accordingly. See BuildScript Note that this repo currently contains only the LLVM Core, see Getting Started with the LLVM System for installing other components like Clang

Usage

Add one of the following to CFLAGS

enable-fco  Enable Function CallSite Obfuscation.Use with LTO  
enable-symobf Enable Symbol Obfuscation.Use with LTO  
enable-bcfobf Enable BogusControlFlow  
enable-cffobf Enable Flattening  
enable-splitobf Enable BasicBlockSpliting  
enable-subobf Enable Instruction Substitution  
enable-allobf Enable All Non-LTO Obfuscation  
enable-adb Enable AntiDebugging Mechanisms

An example of invoking everything from command line would be:
/PATH/TO/OUR/clang -mllvm -enable-allobf -Xlinker -mllvm -Xlinker -enable-fco main.m -flto

TODO

StringEncryption
Generate unobfuscated dSym
Improved CFG Obfuscation Algorithm
Complete Anti-Debuging

Intergrating with Xcode

Compile From Scratch or Download XcodeToolchain From Releases
Copy utils/Hikari.xcplugin to /Applications/Xcode.app/Contents/PlugIns/Xcode3Core.ideplugin/Contents/SharedSupport/Developer/Library/Xcode/Plug-ins/
Under Project Settings. Search for Enable Index-While-Building Functionality to NO. As mentioned by obfuscator-llvm/obfuscator/issues/86
EDIT CFLAGS as you wish.
In Xcode->Toolchains, select Hikari

Troubleshooting

You might run into errors like ld: file not found: /Library/Developer/Toolchains/Hikari.xctoolchain/usr/lib/arc/libarclite_macosx.a. this is due to Xcode's Default Toolchain, located at /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ contains stuff not packed into Hikari.Just copy corresponding directories over

Known Issues

On Darwin seems like __DARWIN_ALIAS_C is messing up symbols, results in a failed dlsym() and thus crush the process.
