About:
Kaitai Struct Compiler is the core engine that processes declarative .ksy format definitions of binary data structures. It compiles these definitions into source code for various programming languages, enabling developers to parse complex binary formats without manual bit-level coding. This tool bridges the gap between format specification and implementation, ensuring consistency and reducing errors.
Key Features:
  • Multi-language code generation (Java, C++, Python, Ruby, etc.)
  • Declarative .ksy format for defining binary structures
  • Support for complex formats including bitfields, conditional fields, and enums
  • Integration with IDEs and build systems
Use Cases:
  • Reverse engineering proprietary file formats
  • Building network protocol parsers
  • Creating parsers for legacy or embedded system data
  • Developing forensic analysis tools
Alternatives:
  • Custom parsers – Manual coding is error-prone and language-specific, while Kaitai provides declarative, cross-language consistency
  • WireShark dissectors – Wireshark focuses on network protocols with a GUI, Kaitai is more general-purpose and generates reusable code
