\"LetsEncrypt
\nLetsEncrypti ettev\u00f5te, mis pakub tasuta SSL-sertifikaate kr\u00fcpteerimiseks, on sunnitud t\u00fchistama teatud sertifikaate.<\/p>\n

<\/a><\/noindex><\/p>\n

Probleem on seotud programmi veaga<\/a><\/noindex> Boulderi haldustarkvaras, mida kasutatakse CA rajamiseks. Tavaliselt toimub DNS CAA kirje kontrollimine koos domeeni omamise kinnitamisega, ja enamik tellijaid saab sertifikaadi kohe p\u00e4rast kontrollimist, kuid tarkvara arendajad on teinud nii, et kontrollimistulemus loetakse m\u00f6\u00f6dunuks veel j\u00e4rgmised 30 p\u00e4eva. M\u00f5nel juhul v\u00f5ib kontrollida kirjeid uuesti otse enne sertifikaadi v\u00e4ljastamist, sealhulgas on vaja uuesti kontrollida CAA kaheksa tundi enne v\u00e4ljastamist, seega tuleb igasuguseid domeene, mis on varem selle ajavahemiku jooksul kontrollitud, uuesti kontrollida.<\/p>\n

<\/p>\n

Mis on vea p\u00f5hjus? Kui sertifikaadi taotlus sisaldab N domeeni, mis vajavad korduskontrolli CAA \u2014 Boulder valis \u00fche neist ja kontrollis seda N korda. Selle tulemusena oli olemas v\u00f5imalus sertifikaadi v\u00e4ljastamiseks, isegi kui hiljem (kuni X+30 p\u00e4eva) t\u00f5stetakse CAA kirje, mis keelab LetsEncrypti sertifikaadi v\u00e4ljastamise.<\/p>\n

<\/p>\n

Sertifikaatide kontrollimiseks on ettev\u00f5te valmistanud veebit\u00f6\u00f6riista<\/a><\/noindex>, mis n\u00e4itab \u00fcksikasjalikku aruannet.<\/p>\n

Edasi tuleb vaadata siin<\/a><\/noindex> oma seerianumbrit, ja kui see on nimekirjas \u2014 soovitatakse sertifikaati(d) uuendada.<\/p>\n
<\/p>\n
Sertifikaatide uuendamiseks saab kasutada certbot'i:<\/p>\n
<\/p>\n
certbot renew --force-renewal<\/code><\/pre>\n
<\/p>\n
Probleem leiti juba 29. veebruaril 2020, probleemi lahendamiseks peatati sertifikaatide v\u00e4ljastamine ajavahemikul 3:10 UTC kuni 5:22 UTC. Siseuuringu kohaselt tehti viga 25. juulil 2019, ettev\u00f5te esitab hiljem p\u00f5hjalikuma aruande.<\/p>\n
<\/p>\n
UPD: sertifikaatide kontrollimise veebiteenus ei pruugi t\u00f6\u00f6tada Venemaa IP-aadressidega.<\/p>\n
