About:
Keystone is a lightweight multi-platform, multi-architecture assembler framework. It provides a unified API for generating machine code for various CPU architectures, including x86, ARM, and MIPS. Its core value lies in its modular design, offering bindings for C, Python, Rust, and other languages, making it ideal for integration into security tools and reverse engineering frameworks.
Key Features:
  • Supports multiple architectures (x86, ARM, MIPS, etc.)
  • Bindings for C, Python, Rust, and Go
  • Lightweight and thread-safe
  • Simple, unified API
Use Cases:
  • Building custom disassemblers or debuggers
  • Implementing JIT compilers
  • Creating shellcode generation tools
  • Reverse engineering and malware analysis
Alternatives:
  • Ghidra – Ghidra is a full-featured suite including a disassembler and decompiler, whereas Keystone focuses solely on assembly.
  • Capstone – Capstone is the companion disassembler framework to Keystone's assembler.
