This does not let you pick which peers get to join. There are some other details involved too, like encrypting some of the metadata in the. Anyone adding the magnet link without the key, would just get encrypted data. To download the torrent in an unencrypted form, you would add the &key= argument to the magnet link, and uTorrent decrypts and encrypts data at the disk boundary (leaving the data on disk in the clear). An encrypted torrent like this is backwards compatible with clients that don't support the feature, but they won't be able to access the data (just help out the swarm and seed it). torrent file would have hashes of the encrypted data. The data integrity checks (sha-1 hashes of pieces) would be done on encrypted blocks and the. encrypted torrentsĪt BitTorrent (in the uTorrent client) we added support for symmetric encryption of torrents at the disk layer:Įverything in the bittorrent engine would operate on encrypted blocks.

The tracker can authenticate every peer connecting to it, but even if the peer list (or one peer) is leaked or guessed, there's still the peer-to-peer authentication, blocking any unauthorized access.īittorrent over SSL has been implemented and deployed. SSL encryption of all peer connections + tracker connections.The ability to pick which peers are let into the swarm by signing their certificate with the swarm root.Authentication of every peer participating.Starting with the strongest system, it is possible to run bittorrent over SSL (it's not supported by many clients, but in a fully controlled deployment it can be done). This is a bittorrent centric answer, because you tagged the question with bittorrent. I'll enumerate a few attempts in decreasing level of 'security'. Since you compare it to https, it seems like a reasonable assumption is that you're looking for authentication and confidentiality. Every answer here seems to have a different interpretation of the question, or rather, a different assumed purpose of the encryption.
