# 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 PHP7.4+, 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`).
