This project implements music de-obfuscation on [.NET](https://dotnet.microsoft.com/), and accelerates the process with [SIMD](https://docs.microsoft.com/en-us/dotnet/standard/simd). The CLI program also uses [Native AOT](https://learn.microsoft.com/en-us/dotnet/core/deploying/native-aot/) feature.

## Licensing

The core library is distributed under [GNU LGPL v2.1](./MusicDecrypto.Library/LICENSE), while the CLI and GUI applications are both distributed under [GNU AGPL v3](./LICENSE).

## Supported formats

You may refer to [the full list](./MusicDecrypto.Library/DecryptoFactory.cs#L23). Please notice that support for `.mgg` and `.mflac` series are partial.

## CLI usage

Drag and drop files and/or directories on the CLI program or run:

`musicdecrypto [options] [...]`

### Options

```

-f, --force-overwrite    Overwrite existing files.

-r, --recursive          Search files recursively.

-x, --extensive          Extend range of extensions to be detected.

-o, --output     Output directory.

```
