Angr is a binary analysis framework and static analysis tool used for reverse engineering compiled binaries. It serves as a binary decompiler and a lifting platform that translates machine code into a common intermediate representation to enable cross-architecture analysis.
The framework integrates a symbolic execution engine and constraint solvers to determine the inputs required to reach specific program states. It also employs untrusted code sandboxing to isolate guest code from the host environment during analysis.
Its capabilities cover control flow and data flow analysis, including the recovery of control flow graphs and taint-based data tracking. The system provides utilities for binary decompilation, value set analysis, and program execution instrumentation.
The project includes mechanisms to compile native library components from source to ensure compatibility with the host operating system.
