Anonymous network I2P 1.8.0 and C++ client i2pd 2.42.0 have been released. I2P is a multi-layer anonymous distributed network operating on top of the regular Internet, actively using end-to-end encryption to guarantee anonymity and isolation. The network is built in P2P mode and is formed thanks to the resources (bandwidth) provided by network users, which makes it possible to do without the use of centrally controlled servers (communications within the network are based on the use of encrypted unidirectional tunnels between the participant and peers).
On the I2P network, you can anonymously create websites and blogs, send instant messages and e-mails, exchange files, and organize P2P networks. To build and use anonymous networks for client-server (websites, chats) and P2P (file exchange, cryptocurrencies) applications, I2P clients are used. The basic I2P client is written in Java and can run on a wide range of platforms such as Windows, Linux, macOS, Solaris, etc. I2pd is an independent C++ implementation of the I2P client and is distributed under a modified BSD license.
The new version of I2P offers an initial implementation of the "SSU2" UDP transport, which significantly improves performance and security. The introduction of SSU2 will completely update the cryptographic stack and get rid of the very slow ElGamal algorithm (ECIES-X25519-AEAD-Ratchet will be used for end-to-end encryption instead of ElGamal/AES+SessionTag).
Other changes include redesigning the configuration wizard in the console and updating Tomcat to version 9.0.62. i2psnark added system tray support and MIME types loading. Removed code with the implementation of the BOB API, which has long been deprecated (users are encouraged to switch to using the SAMv3 protocol).
