OCaml-yara is a Ctypes wrapper that provides OCaml bindings for the YARA matching engine, enabling developers to integrate malware identification capabilities into OCaml applications. The tool serves as a bridge between OCaml programming language and YARA's pattern matching functionality, allowing for file and memory scanning operations within OCaml-based security tools and applications. It offers a programmatic interface for implementing YARA rule-based detection in OCaml environments, supporting the development of custom malware analysis and detection systems. The wrapper maintains compatibility with YARA's core features while providing OCaml-native function calls and data structures for seamless integration into existing OCaml codebases.
