Support for QR codes


There is experimental support for encoding and reading QR codes containing references to IPFS-hosted content. To be able to use the QR features, you need to install the zbar library on your system (on Linux/BSD systems it is widely available, on MacOS you can install it with brew install zbar).

In the filemanager you can access all your QR codes from the QR codes folder, which contains some QR sample files by default.

In the image viewer

When opening an image containing IPFS QR codes, the image viewer will display a special section below the image. For each IPFS object found in the image, its path will be displayed, as well as buttons to open the object and copy its path to the clipboard.

In the clipboard manager

If a clipboard item is an image containing QR codes, a special IPFS QR codes menu will be displayed in the clipboard item’s menu. From this menu you can open each individual object.

Encoding the clipboard stack

The clipboard manager’s QR encoding menu gives you the possibility to QR-encode all the IPFS objects of the current clipboard stack to a single image (RSA self-encrypted or clear). Later on the software could provide the possibility to send QR images encrypted for specific peers.

The clear QR images are not encrypted, and are not immediately announced on the network (they are added to the repository with the offline option). You can announce them later on when you want to.

The resulting images can be found in the QR codes folder in the filemanager (the RSA-encrypted images are stored in the encrypted subfolder).

In the browser

If the page you’re browsing contains an image that contains IPFS QR codes, right-clicking on it will show an IPFS QR codes menu similar to the one displayed in the clipboard manager.

Encoding a pyramid’s IPNS key

The IPNS key of your multihash pyramids can be QR-encoded. Right-click a pyramid and select Generate pyramid’s QR code (the generated image’s filename will contain the IPNS key id).
