Release of the I2P 0.9.36 and C anonymous network - the client i2pd 2.20 with support of the new protocol


The release of the I2P 0.9.36 anonymous network (reference realization on Java) and also release i2pd 2.20 (I2P Daemon), full-function realization of the client of I2P in language C has taken place.

New versions are remarkable addition of support of the new transport NTCP2 protocol. The new protocol is made on the basis of Noise Protocol Framework and in addition uses a hash of HMAC-SHA256 and the system of exchange of keys of x25519 on the basis of elliptic curves. The main features of NTCP2 are an opportunity to effectively resist to the systems of recognition of traffic (DPI) and decrease in load of CPU in the course of work.

Because of application of faster algorithms of enciphering of NTCP2 is suitable for application on the low-power built-in devices, smartphones and home routers. In comparison with earlier offered NTCP protocol in NTCP2 definition not of two, but three keys is required (x25519 key, a key for enciphering and a key for the digital signature), and on delivery keys several calls of HMAC-SHA256 are used. Besides, instead of ElGamal x25519 is applied to coordination of keys, and for enciphering instead of a linking of AES-256-CBC/Adler32 AEAD/Chaha20/Poly1305 is used. For complication of information on length of a package SipHash is in addition used.

NTCP2 will be included by default in the following release of I2P, but it is possible to test him already now, having specified in a configuration of "i2np.ntcp2.enable=true". In I2P the new address NTCP2 is set in old style with addition of additional parameters that allows to accept the NTCP and NTCP2 connections at the same time. In i2pd the address NTCP2 is defined completely separately from the old address NTCP.

Also in release of I2P 0.9.36 are noted the following changes: The mode of ordered loading of files, from the first part to the last is added to the built-in torrent client of I2P Snark; Jetty is updated to the version 9.2.25.v20180606; Productivity of the main transport protocols Is improved; The installer for Windows 10 Is corrected; Small errors Are corrected and optimization of productivity is performed. I2P represents the multilayered anonymous distributed network which is working over the usual Internet actively using through (end-to-end) enciphering guaranteeing anonymity and isolation. In I2P network it is possible to create anonymously the websites and blogs, to send instant messages and e-mail, to exchange files and to organize P2P-networks. The basic I2P-client is written in the Java language and can work at a wide range of platforms, such as Windows, Linux, macOS, Solaris, etc. I2pd represents independent realization of the client of I2P in language C and is distributed under the modified license BSD.
