# sashs/Ropper

Display information about files in different file formats and find gadgets to build rop chains for different architectures (x86/x86_64, ARM/ARM64, MIPS, PowerPC, SPARC64). For disassembly ropper uses the awesome Capstone Framework.

## What it is
Ropper is a Python CLI tool that displays information about binary files (ELF, PE, Mach-O, RAW) and finds ROP/JOP gadgets to build exploit chains across x86/x86_64, ARM/ARM64, MIPS, PowerPC, and SPARC64 architectures. It uses the Capstone framework for disassembly and supports semantic gadget search and automatic ROP chain generation.

## Use cases
- find rop gadgets in a binary
- build rop chains for exploit development
- inspect elf/pe/mach-o binary headers and sections
- search gadgets for arm or mips architectures
- disassemble binary instructions with capstone
- generate execve or mprotect rop chain automatically
- find stack pivot gadgets

## When to choose
- you need a multi-architecture ROP gadget finder for exploit development
- you want binary file inspection (headers, sections, imports, symbols) alongside gadget search
- you need semantic constraint-based gadget search
- you want automatic ROP chain generation for common syscalls

## When to avoid
- you need a full interactive reverse-engineering suite like Ghidra or IDA
- you only need static analysis without gadget hunting
- you require architectures outside the supported list
- you need a GUI-based binary analysis workflow
