stshare - Syncthing encrypted peer file server
Serves files from Syncthing peers that hold encrypted files using untrusted device encryption. This is useful when syncing files to an (untrusted) cloud server, but you still want to be able to hand out 'sharing links' that allow incidental access to specific files. A sharing link only contains the per-file encryption key, so only the requested file can be decrypted by anyone who is able to observe the request.
