It is now possible to install all I2P components using a single package (No Java required). To try out the new installer, click below. This bundle can also be used to configure a Firefox Profile. It will not interfere with an existing I2P installation if one exists. I2P …

I2P is a project to build, deploy, and maintain a network supporting secure and anonymous communication. People using I2P are in control of the tradeoffs between anonymity, reliability, bandwidth usage, and latency.

What Can I Do On The I2P Network? The network provides an application layer for services, applications, and network managment. The network also has its own unique DNS that allows self hosting and mirroring of content from the Internet (Clearnet). The I2P network functions the same way the Internet does.

I2P uses cryptography at several protocol layers for encryption, authentication, and verification. The major protocol layers are: transports, tunnel build messages, tunnel layer encryption, network database messages, and end-to-end (garlic) messages.

The I2P network is a fully encrypted peer-to-peer overlay network. An observer cannot see a message's contents, source, or destination. No one can see where traffic is coming from, where it is going, or what the contents are.

I2P does not encrypt the Internet, neither does Tor - for example, through Transport Layer Security (TLS). I2P and Tor both aim to transport your traffic as-is securely and anonymously over the corresponding network, to its destination.

I2P is designed to allow peers using I2P to communicate with each other anonymously — both sender and recipient are unidentifiable to each other as well as to third parties. For example, today there are both in-I2P web sites (allowing anonymous publishing / hosting) as well as HTTP proxies to the normal web (allowing anonymous web browsing).

A web browser will need to be configured to access sites and services on the I2P network, and to utilize outproxies. Below are walkthroughs for some of the most popular browsers. Firefox Profile for Windows. If you are using Windows, the recommended way of accessing the I2P network is using the Firefox profile.
