Imagine...

The conventional Internet is currently like a system of roads with deep potholes and highwaymen all over the place. Even if you still can use the roads (e.g. send emails, or browse websites) your vehicle might get hijacked, damaged, or long arms might reach into its back and steal your items (data) to use it against you and sell it to others - while you can't even notice the thievery nor accuse and hold the scroungers accountable.

The Internet is broken

Protocols from Ethernet and IP to BGP and X.509 PKI are insecure by default: protecting against address forgery, routers learning metadata, or choosing trustworthy CAs is nontrivial and sometimes impossible.

GNUnet provides privacy by design, improving addressing, routing, naming and content distribution in a technically robust manner - as opposed to ad-hoc designs in place today.

Decentralization is hard

Instead of sharing common components and tools for building P2P systems, every P2P project seems to re-invent the wheel. This heightens the effort and increases the potential number of vulnerabilities.

GNUnet is a metadata-preserving foundation for your application, covering areas from addressing to reliable bidirectional Axolotl-encrypted channels, with advanced routing. Our work is based on continuous research spanning almost two decades.

Metadata is exposed

Your metadata is just as revealing as the actual content; and it gets exposed on the Internet.
Even though transport encryption is increasingly being deployed on the Internet, it still reveals data that can threaten democracy: the identities of senders and receivers, the times, frequency and the volume of communication are all still revealed.
GNUnet addresses these concerns with perfect forward secrecy via ephemeral public key addressing, fixed packet size to hinder traffic analysis, layered encryption, Sybil-resistant routing, and more.

Freedoms are not respected

Today, monitoring increasingly centralized infrastructure, proprietary implementations, traffic shapers and firewalls restrict all of the essential freedoms to various degrees.

GNUnet gives users freedoms to securely access information ("run" the network), to study all aspects of the network's operation ("access the code"), to distribute information ("copy"), as well as the freedom to deploy new applications ("modify").

If you want to know more about the GNUnet please continue reading the about page. There are much more resources, such as the main handbook / reference manual, a bibliography and videos.

You are very welcome to get engaged into the conversation, install GNUnet, use it and contribute.
Be aware that this project is still in an early alpha stage when it comes to software – it is not an easy task to rewrite the whole Internet!

secushare

secushare is creating a decentralized social networking application on top of GNUnet. Using overlay multicast and the extensible PSYC protocol, notifications are distributed end-to-end encrypted to authorized recipients only.

pretty Easy privacy

pretty Easy privacy (p≡p) is creating a usable end-to-end encrypted e-mail solution using opportunistic key exchange. p≡p will use GNUnet to protect metadata and exploit new cryptographic protocols to verify keys.
