<p><b>Turtle</b> was a <a href="/wiki/Free_software" title="Free software">free</a> <a href="/wiki/Anonymous_peer-to-peer" class="mw-redirect" title="Anonymous peer-to-peer">anonymous peer-to-peer</a>

It is not developed anymore. Like other anonymous P2P software, it allows users to share files and otherwise communicate without fear of legal sanctions or censorship.

Each user acts as node in the overlay by running a copy of the Turtle client software. Unlike existing P2P networks, Turtle does not allow arbitrary nodes to connect and exchange information. Instead, each user establishes secure and authenticated channels with a limited number of other nodes controlled by trusted people (friends). </p><p>In the Turtle overlay, both queries and results move hop by hop; the net result is that information is only exchanged between people that trust each other and is always encrypted. Consequently, a snooper or adversary has no way to determine who is requesting / providing information, and what that information is. Given this design, a Turtle network offers a number of useful security properties, such as confined damage in case of node compromise, and resilience against denial of service attacks. </p> <div
