Obfuscator-LLVM is a project initiated in June 2010 by the information security group of the University of Applied Sciences and Arts Western Switzerland of Yverdon-les-Bains (HEIG-VD).

The aim of this project is to provide an open-source fork of the LLVM compilation suite able to provide increased software security through code obfuscation and tamper-proofing. As we currently mostly work at the Intermediate Representation (IR) level, our tool is compatible with all programming languages (C, C++, Objective-C, Ada and Fortran) and target platforms (x86, x86-64, PowerPC, PowerPC-64, ARM, Thumb, SPARC, Alpha, CellSPU, MIPS, MSP430, SystemZ, and XCore) currently supported by LLVM.
