This parser is for the RPM version 3 file format which is the current version of the file format used by RPM 2.1 and later (including RPM version 4.x, which is the current version of the RPM tool). There are historical versions of the RPM file format, as well as a currently abandoned fork (rpm5). These formats are not covered by this specification.
This page hosts a formal specification of RPM package file using Kaitai Struct. This specification can be automatically translated into a variety of programming languages to get a parsing library.
All parsing code for C# generated by Kaitai Struct depends on the C# runtime library. You have to install it before you can parse data.
The C# runtime library is available in the NuGet Gallery. Installation instructions can also be found there.
Parse a local file and get structure in memory:
var data = Rpm.FromFile("path/to/local/file.rpm");
Or parse structure from a byte array:
byte[] someArray = new byte[] { ... };
var data = new Rpm(new KaitaiStream(someArray));
After that, one can get various attributes from the structure by accessing properties like:
data.Lead // => get lead
// This is a generated file! Please edit source .ksy file and use kaitai-struct-compiler to rebuild
using System.Collections.Generic;
