Foi lan\u00e7ado a rede an\u00f4nima I2P 2.0.0 e o cliente em C++ i2pd 2.44.0. O I2P \u00e9 uma rede distribu\u00edda an\u00f4nima em m\u00faltiplas camadas, que funciona sobre a Internet convencional, utilizando ativamente criptografia de ponta a ponta para garantir anonimato e isolamento. A rede \u00e9 constru\u00edda em modo P2P e se forma a partir dos recursos (capacidade de banda) fornecidos pelos usu\u00e1rios da rede, permitindo operar sem servidores gerenciados de forma centralizada (as comunica\u00e7\u00f5es na rede s\u00e3o baseadas em t\u00faneis unidirecionais criptografados entre os participantes e peers). <\/p>\n
Na rede I2P, \u00e9 poss\u00edvel criar sites e blogs de forma an\u00f4nima, enviar mensagens instant\u00e2neas e e-mails, compartilhar arquivos e organizar redes P2P. Para a constru\u00e7\u00e3o e utiliza\u00e7\u00e3o de redes an\u00f4nimas em aplica\u00e7\u00f5es cliente-servidor (sites, chats) e P2P (troca de arquivos, criptomoedas), utilizam-se clientes I2P. O cliente b\u00e1sico I2P \u00e9 escrito em Java e pode operar em uma ampla gama de plataformas, como Windows, Linux, macOS, Solaris etc. O i2pd \u00e9 uma implementa\u00e7\u00e3o independente do cliente I2P em C++ e \u00e9 distribu\u00eddo sob uma licen\u00e7a BSD modificada. <\/p>\n
No I2P 2.0 e i2pd 2.44, foi implementado por padr\u00e3o um novo protocolo de transporte «SSU2», baseado em UDP, que melhora o desempenho e a seguran\u00e7a. A introdu\u00e7\u00e3o do SSU2 permitir\u00e1 uma atualiza\u00e7\u00e3o completa da pilha criptogr\u00e1fica, eliminando o uso do muito lento algoritmo ElGamal (para criptografia de ponta a ponta, em vez de ElGamal\/AES+SessionTag, foi utilizada a combina\u00e7\u00e3o ECIES-X25519-AEAD-Ratchet), reduzindo a sobrecarga em compara\u00e7\u00e3o com o protocolo SSU e melhorando o desempenho em dispositivos m\u00f3veis. <\/p>\n
Outras mudan\u00e7as no I2P 2.0 incluem a implementa\u00e7\u00e3o de autentica\u00e7\u00e3o de proxy baseada em hashes SHA-256 (RFC 7616) no i2ptunnel. A implementa\u00e7\u00e3o do protocolo SSU2 adicionou suporte para migra\u00e7\u00e3o de conex\u00f5es e confirma\u00e7\u00f5es instant\u00e2neas de recebimento de dados. A funcionalidade do determinador de bloqueios m\u00fatuos foi aprimorada. Uma op\u00e7\u00e3o para compress\u00e3o de logs do roteador foi adicionada. <\/p>\n
No i2pd 2.44 foi adicionada a possibilidade de aplicar SSL<\/a>-conex\u00f5es para t\u00faneis com o servidor I2P. Foi implementada a capacidade de proxy para os protocolos SSU2 e NTCP2 (ipv6) atrav\u00e9s de SOCKS5. Adicionadas configura\u00e7\u00f5es MTU (Maximum Transmission Unit) para o protocolo SSU2 (ssu2.mtu4 e ssu2.mtu6). \u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 \u0430\u043d\u043e\u043d\u0438\u043c\u043d\u043e\u0439 \u0441\u0435\u0442\u0438 I2P 2.0.0 \u0438 C++-\u043a\u043b\u0438\u0435\u043d\u0442\u0430 i2pd 2.44.0.
