La autoridad de certificaci\u00f3n sin \u00e1nimo de lucro Let's Encrypt, controlada por la comunidad y que ofrece certificados de forma gratuita a todos los interesados, ha advertido sobre la reducci\u00f3n del per\u00edodo de validez de los certificados TLS de 90 a 64 d\u00edas. A partir del 10 de febrero de 2027, todos los nuevos certificados emitidos y los certificados renovados tendr\u00e1n una validez de 64 d\u00edas, mientras que los certificados de 90 d\u00edas emitidos antes de esta fecha seguir\u00e1n siendo v\u00e1lidos. Adem\u00e1s, a partir del 10 de febrero de 2027, el per\u00edodo de autorizaci\u00f3n se reducir\u00e1 de 30 a 10 d\u00edas, es decir, el tiempo tras la validaci\u00f3n de sus derechos sobre el dominio durante el cual puede emitirse el certificado sin pasar por verificaciones adicionales. Desde el 16 de febrero de 2028, se planea reducir el per\u00edodo de validez de los certificados de 64 a 45 d\u00edas, y el de autorizaci\u00f3n, de 10 d\u00edas a 7 horas.<\/p>\n

La raz\u00f3n de la reducci\u00f3n del per\u00edodo de validez de los certificados son los nuevos requisitos de la asociaci\u00f3n CA\/Browser Forum, elaborados durante la colaboraci\u00f3n entre los fabricantes de navegadores y las autoridades de certificaci\u00f3n. Una reducci\u00f3n similar del per\u00edodo de validez ser\u00e1 implementada por todas las autoridades de certificaci\u00f3n. El CA\/Browser Forum ha establecido como plazo final para la implementaci\u00f3n marzo de 2029, y el tiempo m\u00e1ximo de validez de un certificado ser\u00e1 de 47 d\u00edas. Despu\u00e9s de marzo de 2029, el procesamiento en los navegadores de los nuevos certificados cuya validez supere los 47 d\u00edas dar\u00e1 lugar a un error de tipo 'ERR_CERT_VALIDITY_TOO_LONG'.<\/p>\n

La transici\u00f3n a certificados de corta duraci\u00f3n reducir\u00e1 el tiempo de implementaci\u00f3n de nuevos algoritmos criptogr\u00e1ficos en caso de que se descubran vulnerabilidades y evitar\u00e1 que los atacantes controlen el tr\u00e1fico de la v\u00edctima durante per\u00edodos prolongados o utilicen certificados para phishing en caso de que se filtre un certificado debido a una violaci\u00f3n. La revisi\u00f3n m\u00e1s frecuente de la propiedad del dominio<\/a> y la reducci\u00f3n de la duraci\u00f3n de los certificados tambi\u00e9n disminuir\u00e1n la probabilidad de que un certificado siga siendo v\u00e1lido despu\u00e9s de que la informaci\u00f3n contenida en \u00e9l pierda relevancia y reducir\u00e1n el riesgo de la difusi\u00f3n de certificados mal emitidos.
