This question is inspired by this article (in Russian) about a website called I Know What You Download. From what I understand, they scan the DHT networks and display torrents that any given IP participated in, and although it is sometimes inaccurate, it can provide data on Internet usage, and thus presents a threat to anonymity.

Most people suggest using VPN in order to conceal torrent traffic. However, in another article (also in Russian) same author shares his experience with torrenting over VPN set in Azure. Apparently, he received DMCA notice for torrenting a film (author specifically notes that he did not fully download the film, and everything was done for the sake of experiment). They provided the name and the size of the file, along with IP address and port.

But, some (if not all) torrent-sharing programs have an encryption feature. For instance, Tixati can even enforce encryption for both incoming and outgoing connections:





Question is: what does this feature encrypt? Name of the file, its contents, size? Could it prevent DMCA notices? If not, what does it actually do?

Related: the answer there mentions encryption — does this kind of encryption count?

Think of it like an underground fight club. Encrypting the traffic means nobody on the outside can see you enter or leave, but once you're inside, everybody there knows who you are and can monitor your participation.

This feature is really only useful if you have an ISP that blocks torrent traffic. Encrypting it means it doesn't appear to be torrent traffic, it's just an encrypted stream, but once you get past the ISP and connect to the swarm everybody else participating knows exactly who you are and what you're doing.
