LLVM Code Obfuscation Skill

This skill provides comprehensive knowledge of LLVM-based code obfuscation frameworks and techniques for software protection and anti-reverse engineering.

Core Obfuscation Techniques

Control Flow Obfuscation

Control Flow Flattening (CFF): Transform structured control flow into a single dispatcher loop with state machine
Bogus Control Flow (BCF): Insert opaque predicates and dead code paths
CFG Randomization: Randomize basic block ordering and add fake edges

Data Obfuscation

String Encryption: Encrypt string literals at compile-time, decrypt at runtime
Constant Substitution: Replace constants with complex expressions
Variable Splitting: Split variables into multiple components

Code Transformation
