ROPgadget is a command-line tool designed to search for ROP (Return-Oriented Programming) gadgets within binary files to assist with exploit development and ROP chain construction. The tool supports multiple binary formats including ELF, PE, Mach-O, and Raw formats across various architectures such as x86, x64, ARM, ARM64, PowerPC, SPARC, MIPS, RISC-V 64, and RISC-V Compressed. ROPgadget can be installed via PyPi using pip or compiled from source after installing the Capstone disassembly framework dependency. The tool provides cross-platform compatibility including Windows, iOS, Android, and Cygwin environments. Key functionality includes searching for specific gadgets within binaries, filtering results based on various criteria, and analyzing opcodes and strings within executable files. The tool offers command-line options for specifying target binaries, searching for specific opcodes or strings, setting search depth parameters, and applying filters to refine results. ROPgadget serves as a utility for security researchers and penetration testers who need to identify usable code sequences for constructing ROP chains during binary exploitation activities.
