dec-decode: an iso.dec decoder written in Go

This tool implements the NASOS method of decoding .iso.dec files back into plain .iso files.

History

This tool is also written in Go and born of a frustration that:

1. the NASOS tool is being used to archive ISOs with limited implementations available
2. the original NASOS tool is written as a .NET GUI tool for Windows and is slow on Linux
3. it is hard to find a canonical site for getting the tool
4. It requires downloading unknown binaries

This is a pure Go implementation that documents how this works and should work on all platforms supported by Go. This alleviates all the concerns above.

Installation

You need a working Go installation (I used Go 1.12 on Ubuntu Linux 18.04)

For Go < 1.11 the you will need to install the required libraries manually:

go get github.com/jessevdk/go-flags

Build the tool with:

go install
