I2P 0.9.49

I2P (Invisible Internet Project) or “Invisible Internet Project” is open source software designed to organize a highly stable anonymous, encrypted network, suitable for web browsing, anonymous hosting (creation of anonymous sites, forums and chats, anonymous file sharing servers, etc.). I2P can work with various systems for instant messaging, blogging, file sharing, including through P2P connections (Torrent, eDonkey, Kad, Gnutella), e-mail, VoIP and much more. The addresses in the I2P network are located in the .i2p pseudo-domain space.

The I2P network is characterized by the use of powerful methods for encrypting information, with its P2P architecture and variable intermediaries (hops). In this way, deep anonymization is achieved, MiTM attacks are avoided and it is impossible to replace data packets that remain hidden from the eyes of users.

To access I2P, you need to install a router program that encrypts and decrypts the data, compresses and decompresses the traffic, and forwards it to the peers.
