This page hosts a formal specification of Hashcat Restore file using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All JavaScript code generated by Kaitai Struct depends on the Kaitai Struct runtime library for JavaScript. You must add this dependency to your project before you can parse or serialize any data.
The JavaScript runtime library is available at npm:
npm install kaitai-structSee the usage examples in the JavaScript notes.
Parse structure from an ArrayBuffer:
var arrayBuffer = ...;
var data = new HashcatRestore(new KaitaiStream(arrayBuffer));
After that, one can get various attributes from the structure by accessing fields or properties like:
data.version // => get version
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
