took place the release of the anonymous network i2p 2.1.0 and C ++-client i2pd 2.45.0 . I2P is a multilayer anonymous distributed network operating on top of a regular Internet, actively using through (end-to-end) encryption that guarantees anonymity and isolation. The network is built in P2P mode and is formed thanks to resources (throughput) provided by network users, which allows you to do without the use of centrally controlled servers (communication within the network are based on the use of encrypted unidirectional tunnels between the participant and PEER-AMI).
in the I2P network You can anonymously create web sites and blogs, send instant messages and email, exchange files and organize a P2P network. To build and use anonymous networks for client-server (sites, chats) and P2P (exchange of files, cryptocurrency) applications, I2P clients are used. The basic i2p client is written in Java and can work on a wide range of platforms, such as Windows, Linux, MacOS, Solaris, etc. I2PD is an independent I2P client in C ++ and spreads under the modified BSD license.
In the new issue, work was carried out on errors that have surfaced after the implementation of the SSU2 transport protocol, based on UDP and is characterized by increasing performance and security. Currently, 60% of I2P network routers have already been transferred to SSU2. The transition to SSU2 will fully update cryptographic stack, get rid of the use of a very slow Elgamal algorithm (for end-to-end encryption instead of ecies-x25519-aead-ratchet ) , reduce overhead costs compared to the SSU protocol and improve work on mobile devices. Errors eliminated in I2P 2.1.0 were mainly insignificant or manifested in a rare set of circumstances, and led to a decrease in network performance.
Of the changes that are not related to the elimination of changes, the addition of additional tabs with information about the condition and blocked nodes is allocated to the page /Peers. The i2ptunnel updated encryption settings, Torsocks support was added and the possibility of broadcasting SOCKS tunnels in HTTP Proxes that support Connect. For routers, the code is updated to determine and control overload. In transport, SSU processed the definition of symmetrical nat.
