V \u00f6\u00f6kogumid<\/a><\/noindex> Firefox vaikimisi on v\u00e4lja l\u00fclitatud<\/a><\/noindex> toetab protokolle TLS 1.0 ja TLS 1.1 (seade security.tls.version.min on seatud v\u00e4\u00e4rtusele 3, mis m\u00e4\u00e4rab TLS 1.2 miinimumn\u00f5udeks). Stabiliseeritud v\u00e4ljalaskedes plaanitakse TLS 1.0\/1.1 v\u00e4lja l\u00fclitada m\u00e4rtsis 2020. Chrome'is l\u00f5petatakse TLS 1.0\/1.1 tugi Chrome 81-s, mis on oodatud jaanuaris 2020. <\/p>\n

TLS 1.0 spetsifikatsioon avaldati jaanuaris 1999. Seitsme aasta p\u00e4rast ilmus TLS 1.1 v\u00e4rskendus, mis t\u00f5i kaasa turvaparandusi, mis on seotud initsialiseerimisvektorite ja t\u00e4iendava t\u00e4itmise genereerimisega. Praegu arendab IETF (Internet Engineering Task Force), mis vastutab protokollide ja interneti arhitektuuri arendamise eest,
\narendab<\/a><\/noindex> spetsifikatsiooni mustandi, mis viib protokollid TLS 1.0\/1.1 aegunud kategooriasse. Vastavalt teenuse SSL Pulse<\/a><\/noindex> 3. septembri seisuga toetab TLS 1.2 95.8% kaitstud \u00fchenduste loomisega veebisaitidest, samas kui TLS 1.3 toetab 17.7%. TLS 1.1 on lubatud 75.5% HTTPS-saitidest ja TLS 1.0 puhul on see 65.5%.<\/p>\n

TLS 1.0\/1.1 peamisteks probleemideks on kaasaegsete kr\u00fcptos\u00fcsteemide (nt ECDHE ja AEAD) puudumine ning n\u00f5ue vanade kr\u00fcptode toetamiseks, mille usaldusv\u00e4\u00e4rsus on kaasaegses arvutustehnikas k\u00fcsim\u00e4rgi all (n\u00e4iteks n\u00f5utakse TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA toetust, andmete terviklikkuse ja autentimise kontrollimisel kasutatakse MD5-d ja SHA-1-d). Vananenud algoritmide toetus on juba viinud selliste r\u00fcnnakute tekkimiseni nagu
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> ja FREAK<\/a><\/noindex>. Siiski ei olnud need probleemid otseselt protokolli haavatavused ja need suleti protokollide rakenduste tasemel. TLS 1.0\/1.1 protokollides endis ei ole kriitilisi haavatavusi, mida saaks kasutada praktiliste r\u00fcnnakute l\u00e4biviimiseks.<\/p>\n
