Making Hetzner Storage Box authentication make sense

The documentation for this is pretty terrible and we had to figure this out by trial and error.

The storage box has a password, which is secret and random if not provided. It can be reset to an arbitrary one in the console ("Reset password" in the dropdown menu). Cannot be disabled. It's the only way to use WebDAV and SMB. Always accepted by SSH (and thus SFTP) on either port. It is the only way to recover a storage container you have locked yourself out of after losing SSH keys.

The SSH server on port 22 rejects shell, but it allows spawning the SFTP backend. Requests for any other command or subsystem seem to fail, so it seems to be made specifically for SFTP use.

The SSH server on port 23 offers a limited shell (rsh) with rsync, restic and a few other whitelisted commands. No redirections, pipes or other common shell features you'd expect. (dd is whitelisted, so yo

About YUV formats

First of all: YUV pixel formats and Recommended 8-Bit YUV Formats for Video Rendering. Chromium's source code contains good documentation about those formats too: chromium/src/media/base/video_types.h and chromium/src/media/base/video_frame.cc (search for RequiresEvenSizeAllocation(), NumPlanes() and those kinds of functions).

YUV?

You can think of an image as a superposition of several planes (or layers in a more natural language). YUV formats have three planes: Y, U, and V.

Y is the luma plane, and can be seen as the image as grayscale. U and V are reffered to as the chroma planes, which are basically the colours. All the YUV formats have these three planes, and differ by the different orderings of them.
