toobz

===

A Go implementation of un-zbooting an EFI zboot image (mainly for arm64).

## Why?

Run into an image with `file` output like

```

PE32+ executable (EFI application) Aarch64 (stripped to external PDB), for MS Windows

```

or?

```

PE32+ executable (EFI application) RISC-V 64-bit (stripped to external PDB), for MS Windows

```

These files need to be unpacked in a few cases where the raw kernel is desired.

There are other formats and types of similar looking files (e.g. sectioned) that

`toobz` does not currently support.

## Build

Clone and run

```

make

```

## Usage

To extract an image

```

toobz -in  -out 

```

To extract and decompress an image:

```

toobz -in  -out  -decompress

```

## Reference

This is a Go re-implementation of [unzboot](https://github.com/eballetbo/unzboot) which is actually an

implementation derived from

[qemu](https://github.com/qemu/qemu/blob/master/hw/core/loader.c) both of which

are written in C.
