\"ODesenvolvedores do projeto Chromium fizeram uma altera\u00e7\u00e3o<\/a><\/noindex>, que estabelece o prazo m\u00e1ximo de vida dos certificados TLS em 398 dias (13 meses).<\/p>\n

A condi\u00e7\u00e3o se aplica a todos os certificados de servidor p\u00fablico emitidos ap\u00f3s 1\u00ba de setembro de 2020. Se um certificado n\u00e3o estiver em conformidade com essa regra, o navegador o rejeitar\u00e1 como inv\u00e1lido, especificamente retornando o erro ERR_CERT_VALIDITY_TOO_LONG<\/code>.<\/p>\n

Para os certificados recebidos at\u00e9 1\u00ba de setembro de 2020, a confian\u00e7a ser\u00e1 mantida e limitada a 825 dias<\/a><\/noindex> (2,2 anos), como acontece atualmente.
\n<\/a><\/noindex>
\nAnteriormente, a limita\u00e7\u00e3o do prazo m\u00e1ximo de validade dos certificados foi implementada pelos desenvolvedores dos navegadores Firefox e Safari. A altera\u00e7\u00e3o tamb\u00e9m entra em vigor em 1\u00ba de setembro<\/a><\/noindex>.<\/p>\n

Isso significa que sites que utilizam certificados SSL\/TLS com prazos de validade longos, emitidos ap\u00f3s o limite, apresentar\u00e3o erros de privacidade nos navegadores.<\/p>\n

\"O
\n
\nA nova pol\u00edtica foi anunciada primeiro pela Apple em uma reuni\u00e3o do f\u00f3rum CA\/Browser em fevereiro de 2020<\/a><\/noindex>. Ao implementar a nova regra, a Apple prometeu aplicar isso em todos os dispositivos iOS e macOS. Isso pressionar\u00e1 administradores de sites e desenvolvedores a garantir que seus certificados atendam aos requisitos.<\/p>\n

A redu\u00e7\u00e3o do prazo de validade dos certificados tem sido discutida por v\u00e1rios meses entre a Apple, Google e outros participantes do CA\/Browser. Esta pol\u00edtica tem suas vantagens e desvantagens.<\/p>\n

O objetivo desse passo \u00e9 aumentar a seguran\u00e7a do site, garantindo que os desenvolvedores usem certificados com os mais recentes padr\u00f5es criptogr\u00e1ficos, e reduzir a quantidade de certificados antigos e esquecidos, que podem ser potencialmente roubados e reutilizados para phishing e ataques maliciosos por meio de downloads. Se os criminosos conseguissem quebrar a criptografia do padr\u00e3o SSL\/TLS, certificados de curta dura\u00e7\u00e3o permitiriam que as pessoas migrassem para certificados mais seguros em cerca de um ano.<\/p>\n

A redu\u00e7\u00e3o do per\u00edodo de validade dos certificados tem algumas desvantagens. Foi observado que, ao aumentar a frequ\u00eancia de substitui\u00e7\u00e3o dos certificados, a Apple e outras empresas tamb\u00e9m complicam um pouco a vida dos propriet\u00e1rios de sites e das empresas que precisam gerenciar certificados e conformidade.<\/p>\n

Por outro lado, o Let’s Encrypt e outros centros de certifica\u00e7\u00e3o incentivam os webmasters a implementar procedimentos automatizados para a atualiza\u00e7\u00e3o de certificados. Isso reduz as despesas operacionais e o risco de erros \u00e0 medida que a frequ\u00eancia de substitui\u00e7\u00e3o de certificados aumenta.<\/p>\n

Como \u00e9 sabido, o Let’s Encrypt emite certificados HTTPS gratuitos, com validade de 90 dias, e fornece ferramentas para automatizar a renova\u00e7\u00e3o. Assim, esses certificados se encaixam ainda melhor na infraestrutura geral \u2014 \u00e0 medida que os navegadores imp\u00f5em limites ao prazo m\u00e1ximo de validade.<\/p>\n

Essa mudan\u00e7a foi submetida a vota\u00e7\u00e3o pelos membros da associa\u00e7\u00e3o CA\/Browser Forum, mas a decis\u00e3o n\u00e3o foi aprovada devido ao desacordo entre os centros de certifica\u00e7\u00e3o.<\/a><\/noindex>.<\/p>\n
