What type of encryption are used for instance, Protocol encryption (PE), message stream encryption (MSE) or protocol header encrypt (PHE) or something else?

Also, are these all enabled by default or only some.

Thanks

That's libtorrent territory (qbt's backend) but i guess it causes no harm to ask here, maybe someone will know.

I supposed you've already read this (don't know how accurate it is):

MSE/PE is implemented in BitComet, BitTornado, Deluge, Flashget, KTorrent, libtorrent (used by various BitTorrent clients not limited to QBitTorrent), Mainline, µTorrent, qBittorrent, rTorrent, Transmission, Tixati and Vuze. PHE was implemented in old versions of BitComet. Similar protocol obfuscation is supported in up-to-date versions of some other (non-BitTorrent) systems including eMule.[1]

Yes thanks, I have seen that already and was also wondering how accurate it is.

So, all of the networking stuff is managed by libtorrent, is that right.
