Sandboxed version of the [libarchive](https://www.libarchive.org/) minitar [example](https://github.com/libarchive/libarchive/blob/master/examples/minitar/minitar.c) using [Sandboxed API](https://github.com/google/sandboxed-api).
## Build
First, run `git submodule update --init --recursive` to update submodules.
After this, run the following commands:
`mkdir -p build && cd build`
`cmake .. -G Ninja`
`cmake --build .`
The example binary file can be found at `build/examples/sapi_minitar` and the unit tests at `build/test/sapi_minitar_test`.

## Examples
In this project, the minitar example is sandboxed.
The code is found in the **examples** directory and is structured as follows:
- **sapi_minitar_main.cc** - ***main*** function of the minitar tool. This is mostly similar to the original example.
- **sapi_minitar.h** and **sapi_minitar.cc** - The two main functions (***create*** and ***extract***) and also other helper functions.
- **sandbox.h** - Custom security policies, depending on the whether the user creates or extracts an archive.
On top of that, unit tests can be found in the **test/minitar_test.cc** file.
## Usage
The unit tests can be executed with `./build/test/sapi_minitar_test`.
The **sapi_minitar** command line tool can be used in the same way as the original example. It is also similar to the [tar](https://man7.org/linux/man-pages/man1/tar.1.html) command, only with fewer options:
