Os desenvolvedores do projeto Tor publicaram a vers\u00e3o Arti 2.0.0, a vers\u00e3o oficialmente mantida do conjunto de ferramentas Tor, escrita na linguagem Rust. A implementa\u00e7\u00e3o \u00e9 considerada adequada para uso por usu\u00e1rios comuns, garantindo o mesmo n\u00edvel de privacidade, usabilidade e estabilidade que a implementa\u00e7\u00e3o principal em C. Quando o c\u00f3digo em Rust atingir um n\u00edvel capaz de substituir completamente a vers\u00e3o em C, os desenvolvedores pretendem conferir ao Arti o status de implementa\u00e7\u00e3o principal do Tor e gradualmente interromper o suporte \u00e0 vers\u00e3o em C. O c\u00f3digo \u00e9 distribu\u00eddo sob as licen\u00e7as Apache 2.0 e MIT. <\/p>\n
O Arti foi inicialmente desenvolvido em forma de uma biblioteca modular embut\u00edvel que pode ser utilizada por diferentes aplicativos. Durante o projeto do Arti, a experi\u00eancia anterior no desenvolvimento do Tor foi considerada, evitando assim problemas arquitet\u00f4nicos conhecidos associados ao fato de que a implementa\u00e7\u00e3o em C foi projetada inicialmente como um proxy SOCKS e depois adaptada a outras necessidades. <\/p>\n
Al\u00e9m da moderniza\u00e7\u00e3o da arquitetura, a raz\u00e3o para reescrever o Tor em Rust foi o desejo de aumentar a seguran\u00e7a do c\u00f3digo usando uma linguagem que proporciona um trabalho seguro com a mem\u00f3ria. Segundo os desenvolvedores do Tor, o uso da linguagem Rust sem blocos «unsafe» permitir\u00e1 evitar pelo menos metade de todas as vulnerabilidades t\u00edpicas no projeto. Al\u00e9m disso, espera-se que Rust aumente a velocidade de desenvolvimento devido \u00e0 expressividade da linguagem e \u00e0s garantias rigorosas, permitindo economizar tempo com verifica\u00e7\u00f5es duplas e a escrita de c\u00f3digo desnecess\u00e1rio. <\/p>\n
Uma mudan\u00e7a significativa no n\u00famero da vers\u00e3o foi feita de acordo com o modelo de versionamento sem\u00e2ntico utilizado pelo projeto e est\u00e1 relacionada a altera\u00e7\u00f5es que quebram a compatibilidade retroativa. O suporte \u00e0s configura\u00e7\u00f5es proxy.socks_port e proxy.dns_port, que haviam sido previamente marcadas como obsoletas, foi encerrado, sendo substitu\u00eddas pelas configura\u00e7\u00f5es proxy.socks_listen e proxy.dns_listen. O suporte \u00e0 antiga sintaxe de defini\u00e7\u00e3o de diret\u00f3rios (Directory Authority) foi tamb\u00e9m descontinuado. servidores<\/a> Todos os interfaces de programa\u00e7\u00e3o do pacote crate arti foram marcados como experimentais, pois h\u00e1 planos de mov\u00ea-los para outros pacotes crate ou exclu\u00ed-los. <\/p>\n A nova funcionalidade inclui suporte a um novo tipo de soquete «inet-auto» para designa\u00e7\u00e3o autom\u00e1tica de portas TCP n\u00e3o utilizadas para o servidor RPC. A implementa\u00e7\u00e3o de funcionalidades para rel\u00e9s e servidores de diret\u00f3rios foi continuada. Para os servidores de diret\u00f3rios, foram realizados trabalhos de gerenciamento de certificados, incluindo a adi\u00e7\u00e3o de recursos para upload, verifica\u00e7\u00e3o e armazenamento de certificados. Para os rel\u00e9s, foi implementada uma nova arquitetura modular para gerenciar cadeias de n\u00f3s, suporte \u00e0 cria\u00e7\u00e3o de canais de comunica\u00e7\u00e3o com outros rel\u00e9s, suporte ao processamento de solicita\u00e7\u00f5es de estabelecimento de conex\u00e3o e a possibilidade de opera\u00e7\u00e3o do rel\u00e9 no papel de servidor<\/a> conex\u00f5es TLS.
