I2P

I2P is an anonymous network layer that allows applications to send messages to each other pseudonymously and securely. It is an overlay network that uses cryptography and tunnels to hide the identity and location of users.

What is I2P?

I2P (Invisible Internet Project) is an anonymous network layer designed to allow applications to communicate securely and privately. Some key aspects of I2P include:

  • Anonymity - I2P obscures the identity and location of users by routing traffic through an overlay network of peer-to-peer tunnels.
  • End-to-end encryption - Messages sent through I2P are encrypted from the sender to endpoint, protecting communication content confidential.
  • Censorship resistance - The decentralized nature of I2P makes it resistant to censorship and surveillance.
  • Open source - I2P is developed as a free and open source project maintained by volunteers.

I2P allows people to host services like websites, chat servers, and file sharing safely by shielding the server operator and clients from surveillance. Some common applications built on I2P include I2P-Bote (secure email), Susimail (webmail), and I2P torrent tracker. The anonymity and privacy properties make I2P suitable for those needing high security and resistance against monitoring.
