Kaitai Struct

🧬 Reverse Engineering · Scala

Kaitai Struct is a declarative language and toolset for describing binary data structures. You define a format specification in YAML (.ksy file) describing fields, their types, conditions, and relationships, then compile it into parser source code for any of 12+ supported languages (C++, C#, Go, Java, JavaScript, Lua, Nim, Perl, PHP, Python, Ruby, Swift). The Web IDE provides interactive visualization of binary files with real-time parsing. The format gallery contains hundreds of pre-built specifications for common formats (ELF, PE, ZIP, PNG, etc.). Kaitai eliminates manual binary parsing code and ensures consistency across implementations.
