# LibreQR

A PHP Web interface for generating QR codes.

## Demo

A LibreQR instance is available at <https://qr.antopie.org>.

## Installation

### Generic

Just place this source code in a Web server with PHP8.0+, extensions `gd`, `mbstring` and `iconv`, and writing rights on the `css/` directory.

#### Security hardening

##### HTTP headers

Your HTTP server can reply the following headers:
```
Content-Security-Policy: default-src 'none'; img-src 'self' data:; style-src 'self'; frame-ancestors 'none'; form-action 'self';
Referrer-Policy: no-referrer
```

##### PHP-FPM chroot

LibreQR can be chrooted using PHP-FPM.

### YunoHost

There is [a package](https://code.antopie.org/miraty/qr_ynh/) for [YunoHost](https://yunohost.org/).

For historical reasons, LibreQR is technically named `qr` in YunoHost.

You can install it from the WebAdmin or with this command :

```
sudo yunohost app install qr
```

## Themes

Themes are located in `themes/*`, the default theme is in `themes/libreqr/`.

You can customize your LibreQR instance look by changing the colors in `theme.php`, the logo in `logo.less` or the icons in `icons/<size>.png` (then list the sizes in `theme.php`).
