A empresa Google adicionou<\/a><\/noindex> na base de c\u00f3digo principal do Android o c\u00f3digo com suporte embutido para VPN WireGuard<\/a><\/noindex>. O c\u00f3digo WireGuard foi transferido para a modifica\u00e7\u00e3o do n\u00facleo Linux 5.4<\/a><\/noindex>, desenvolvido para o futuro lan\u00e7amento da plataforma Android 12, a partir do n\u00facleo Linux principal 5.6<\/a><\/noindex>, que originalmente continha aprovada<\/a><\/noindex> WireGuard. O suporte ativo a WireGuard no n\u00edvel do n\u00facleo est\u00e1 habilitado por padr\u00e3o<\/a><\/noindex>. <\/p>\n

At\u00e9 agora, os desenvolvedores do WireGuard para Android ofereceram<\/a><\/noindex> um aplicativo m\u00f3vel, que j\u00e1 foi removido<\/a><\/noindex> pela empresa Google da loja Google Play devido a um link para a p\u00e1gina de doa\u00e7\u00f5es no site do projeto, que violava as regras de pagamento (doa\u00e7\u00f5es s\u00e3o consideradas inadmiss\u00edveis se coletadas por uma organiza\u00e7\u00e3o sem fins lucrativos n\u00e3o registrada).<\/p>\n

Lembre-se de que a VPN WireGuard \u00e9 implementada com base em m\u00e9todos de criptografia modernos, oferece desempenho muito alto, \u00e9 f\u00e1cil de usar, livre de complica\u00e7\u00f5es e provou-se eficaz em v\u00e1rias implementa\u00e7\u00f5es de grande escala que lidam com grandes volumes de tr\u00e1fego. O projeto est\u00e1 em desenvolvimento desde 2015, passou por auditoria e verifica\u00e7\u00e3o formal<\/a><\/noindex> dos m\u00e9todos de criptografia aplic\u00e1veis. No WireGuard, a conceito de roteamento baseado em chaves de criptografia \u00e9 utilizado, o que implica a vincula\u00e7\u00e3o de uma chave privada a cada interface de rede e a aplica\u00e7\u00e3o de chaves p\u00fablicas para estabelecer conex\u00f5es.<\/p>\n

A troca de chaves p\u00fablicas para estabelecer a conex\u00e3o \u00e9 feita de forma semelhante ao SSH. Para a negocia\u00e7\u00e3o de chaves e a conex\u00e3o sem iniciar um daemon separado no espa\u00e7o do usu\u00e1rio, utiliza-se o mecanismo Noise_IK do Noise Protocol Framework<\/a><\/noindex>, semelhante \u00e0 manuten\u00e7\u00e3o de authorized_keys no SSH. A transmiss\u00e3o de dados \u00e9 feita atrav\u00e9s da encapsula\u00e7\u00e3o em pacotes UDP. Suporta a mudan\u00e7a de endere\u00e7o IP do servidor VPN (roaming) sem desconectar a conex\u00e3o, com reconfigura\u00e7\u00e3o autom\u00e1tica do cliente.<\/p>\n

Para criptografia \u00e9 utilizado<\/a><\/noindex> o cifra de fluxo ChaCha20<\/a><\/noindex> e algoritmo de autentica\u00e7\u00e3o de mensagens (MAC) Poly1305<\/a><\/noindex>, desenvolvidos por Daniel Bernstein (Daniel J. Bernstein<\/a><\/noindex>), Tanja Lange
\n(Tanja Lange) e Peter Schwabe (Peter Schwabe). ChaCha20 e Poly1305 s\u00e3o posicionados como alternativas mais r\u00e1pidas e seguras ao AES-256-CTR e HMAC, cuja implementa\u00e7\u00e3o de software permite alcan\u00e7ar tempos de execu\u00e7\u00e3o fixos sem a necessidade de suporte de hardware especial. Para a gera\u00e7\u00e3o da chave secreta compartilhada, utiliza-se o protocolo de Diffie-Hellman em curvas el\u00edpticas na implementa\u00e7\u00e3o Curve25519<\/a><\/noindex>, tamb\u00e9m sugerido por Daniel Bernstein. O algoritmo \u00e9 usado para hash BLAKE2s (RFC7693)<\/a><\/noindex>. <\/p>\n
