# PyMinusone

It's a `python` wrapper for `minusone`.

$$\textit{obfuscation}^{-1}$$

Reverse operation of script obfuscation

## Description

MinusOne is a deobfuscation engine focused on scripting languages. MinusOne is based on [tree-sitter](https://tree-sitter.github.io/tree-sitter/) for parsing, and will apply a set of rules to infer node values and simplify expressions.

MinusOne supports the following languages:
* Powershell

By taking the following example from [`Invoke-Obfuscation`](https://github.com/gh0x0st/Invoke-PSObfuscation/blob/main/layer-0-obfuscation.md#final-payload):

```

It will produce the following output :

```powershell
Write-Host "MinusOne is the best script linter"
```

## Build

`pyminusone` use `maturin`. To build `pyminusone` you need `maturin` first :

```
pip install maturin
```

Then call `maturin`:

```
maturin build
```

## Use

```
import pyminusone
pyminusone.deobfuscate_powershell("1+2")
"3"
```

HTML renderer:

```
import pyminusone
pyminusone.deobfuscate_powershell_html("1+2")
'<span class="number">3</span>\n'
```
