Ronin

Ronin is a comprehensive free and open-source Ruby toolkit designed for security research, exploit development, and network reconnaissance. It provides an extensive collection of libraries and CLI utilities covering DNS lookups, HTTP interaction, binary data manipulation, cryptographic operations, exploit scaffolding, and payload generation, all unified under a consistent Ruby API. Security researchers, CTF players, and penetration testers use Ronin as a scriptable platform for rapidly prototyping custom security tools, automating reconnaissance tasks, and developing exploits without building everything from scratch. The toolkit supports third-party code distribution through git repositories, includes an ActiveRecord-backed database for storing and querying reconnaissance data, and provides an interactive console for ad-hoc security research, making it a Ruby-native alternative to frameworks like Metasploit for operators who prefer Ruby's expressiveness.
