Ap\u00f3s cada fase, o processamento de novos certificados que n\u00e3o atendem aos crit\u00e9rios mencionados resultar\u00e1 em erros de navegador \"ERR_CERT_VALIDITY_TOO_LONG\". Anteriormente, os fabricantes de navegadores conseguiram defender a redu\u00e7\u00e3o gradual do tempo de validade dos certificados de 8 anos para 398 dias (13 meses).    <\/p>\n<p>A nova redu\u00e7\u00e3o do tempo de validade dos certificados TLS foi aprovada por 29 membros, 6 se abstiveram e ningu\u00e9m votou contra. Entre os membros que votaram a favor est\u00e3o: Apple, Google, Microsoft, Mozilla, Amazon, Asseco Data Systems SA (Certum), Buypass AS, Certigna (DHIMYOTIS), Certinomis, DigiCert, Disig, D-TRUST, eMudhra, Fastly, GlobalSign, GoDaddy, HARICA, iTrusChina, Izenpe, NAVER Cloud Trust Services, OISTE Foundation, Sectigo, SHECA, SSL.com, SwissSign, Telia Company, TrustAsia, VikingCloud, Visa. Os membros que se abstiveram foram: Entrust, IdenTrust, Japan Registry Services, SECOM Trust Systems, TWCA.      <\/p>\n<p>A gera\u00e7\u00e3o de certificados de curta dura\u00e7\u00e3o deve permitir a implementa\u00e7\u00e3o mais r\u00e1pida de novos algoritmos criptogr\u00e1ficos em caso de vulnerabilidades nos atuais, al\u00e9m de reduzir as amea\u00e7as \u00e0 seguran\u00e7a. Por exemplo, no caso de uma vazamento de certificado devido a um ataque, os certificados de curta dura\u00e7\u00e3o impedir\u00e3o que os invasores controlem o tr\u00e1fego da v\u00edtima por longos per\u00edodos ou utilizem os certificados para phishing. A valida\u00e7\u00e3o mais frequente e a redu\u00e7\u00e3o dos prazos de validade dos certificados tamb\u00e9m diminuir\u00e3o a probabilidade de que um certificado continue v\u00e1lido ap\u00f3s a perda de relev\u00e2ncia das informa\u00e7\u00f5es contidas nele e reduzir\u00e3o o risco de dissemina\u00e7\u00e3o de certificados mal emitidos.      <\/p>\n<p>Al\u00e9m disso, os certificados de curta dura\u00e7\u00e3o servir\u00e3o como um incentivo para a implementa\u00e7\u00e3o de sistemas autom\u00e1ticos de gerenciamento de certificados, isentos do fator humano. No entanto, a elimina\u00e7\u00e3o da pr\u00e1tica de atualiza\u00e7\u00e3o manual dos certificados pode levar a consequ\u00eancias negativas. Observa-se que alguns dispositivos, que permitem o carregamento de certificados apenas de forma manual, podem permanecer com certificados inv\u00e1lidos devido \u00e0 dificuldade de organizar a atualiza\u00e7\u00e3o manual a cada um m\u00eas e meio. A mudan\u00e7a tamb\u00e9m pode impactar negativamente os neg\u00f3cios dos centros de certifica\u00e7\u00e3o que n\u00e3o oferecem API para a emiss\u00e3o autom\u00e1tica de certificados.<br \/>\n<br
