W nocnych wersjach<\/a><\/noindex> Firefox domy\u015blnie zosta\u0142a wy\u0142\u0105czona<\/a><\/noindex> wsparcie dla protoko\u0142\u00f3w TLS 1.0 i TLS 1.1 (ustawienie security.tls.version.min ustawione na warto\u015b\u0107 3, co oznacza, \u017ce TLS 1.2 jest minimaln\u0105 wersj\u0105). W stabilnych wydaniach planuje si\u0119 wy\u0142\u0105czenie TLS 1.0\/1.1 w marcu 2020 roku. W przegl\u0105darce Chrome wsparcie TLS 1.0\/1.1 zostanie zako\u0144czone w Chrome 81, kt\u00f3ry jest planowany na stycze\u0144 2020 roku. <\/p>\n

Specyfikacja TLS 1.0 zosta\u0142a opublikowana w styczniu 1999 roku. Siedem lat p\u00f3\u017aniej wydano aktualizacj\u0119 TLS 1.1 z poprawkami bezpiecze\u0144stwa zwi\u0105zanymi z generowaniem wektor\u00f3w inicjalizacji i dope\u0142nienia. Obecnie komitet IETF (Internet Engineering Task Force), kt\u00f3ry zajmuje si\u0119 rozwojem protoko\u0142\u00f3w i architektury internetu,
\nrozwija<\/a><\/noindex> opracowuje projekt specyfikacji, kt\u00f3ra klasyfikuje protoko\u0142y TLS 1.0\/1.1 jako przestarza\u0142e. Wed\u0142ug danych serwisu SSL Pulse<\/a><\/noindex> na dzie\u0144 3 wrze\u015bnia protok\u00f3\u0142 TLS 1.2 wspiera 95,8% stron internetowych zezwalaj\u0105cych na nawi\u0105zywanie bezpiecznych po\u0142\u0105cze\u0144, a TLS 1.3 \u2013 17,7%. Po\u0142\u0105czenia przez TLS 1.1 akceptuje 75,5% witryn HTTPS, a TLS 1.0 \u2013 65,5%.<\/p>\n

G\u0142\u00f3wnymi problemami TLS 1.0\/1.1 jest brak wsparcia dla nowoczesnych szyfr\u00f3w (np. ECDHE i AEAD) oraz wym\u00f3g wsparcia dla starych szyfr\u00f3w, kt\u00f3rych niezawodno\u015b\u0107 w obecnych czasach wzbudza w\u0105tpliwo\u015bci (np. wymaga si\u0119 wsparcia TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, a do weryfikacji integralno\u015bci i autoryzacji stosuje si\u0119 MD5 oraz SHA-1). Wsparcie przestarza\u0142ych algorytm\u00f3w ju\u017c prowadzi\u0142o do takich atak\u00f3w jak
\nROBOT<\/a><\/noindex>, DROWN<\/a><\/noindex>, BEAST<\/a><\/noindex>, Logjam<\/a><\/noindex> i FREAK<\/a><\/noindex>. Niemniej jednak, te problemy nie by\u0142y bezpo\u015brednimi lukami w protokole i by\u0142y eliminowane na poziomie jego implementacji. W samych protoko\u0142ach TLS 1.0\/1.1 nie ma krytycznych luk, kt\u00f3re mo\u017cna wykorzysta\u0107 do przeprowadzenia praktycznych atak\u00f3w.<\/p>\n
