Encrypts the message in multiple layers.

The result is that the number of peers relaying each end to end message is the absolute minimum necessary to meet both the sender's and the receiver's threat model. In turn, when a client wants to send a message to another client, the client passes that message out one of their outbound tunnels targeting one of the other client's inbound tunnels, eventually reaching the destination.Įvery participant in the network chooses the length of these tunnels, and in doing so, makes a tradeoff between anonymity, latency, and throughput according to their own needs. To hide the sent messages, each client application has their I2P 'router' build a few inbound and outbound 'tunnels' - a sequence of peers that pass messages in one direction (to and from the client, respectively). I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other.Īll communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ('destinations') are cryptographic identifiers (essentially a pair of public keys).

Protect your clients: Whether you are a large business or a single Android app developer, I2P can help you to secure your communications.Providing end-to-end encryption for users to communicate.

Show your users that you care about their privacy: Websites can easily be made accessible inside I2P.

Encrypt your emails: Bote is a high-latency encrypted email system that runs inside I2P.

Browse I2P eepsites: The browser configuration guide inside the I2P app will help you to start browsing websites inside I2P.

All data is wrapped with several layers of encryption, and the network is both distributed and dynamic, with no trusted parties. It offers a simple layer that identity-sensitive applications can use to securely communicate. I2P is a separate anonymizing network inside the Internet. This is similar to proxy apps like Tor.īut I2P is not a proxy - it is an ecosystem.

I2P protects your communication from dragnet surveillance and monitoring by third parties such as ISPs.
