Please before reading this thread, read Client file format.
Since BitTorrent clients are updated regularly, i'll post the default file template for qbittorrent. And will list any changes for a particular version against this default template.

If you want to get the "user-agent", "peer_id prefix" and "key algorithm" for the latest qBittorrent release you can also download and use my bash script that parse the qBittorrent source code from Github, download here
Download both qBittorrent.sh and libtorrent_funcs.sh and then run qBittorrent.sh with bash.
