Spolo\u010dnos\u0165 GitHub sa rozhodla ukon\u010di\u0165 podporu protokolov TLS 1.0 a 1.1 v repozit\u00e1ri bal\u00ed\u010dkov NPM a na v\u0161etk\u00fdch str\u00e1nkach s\u00favisiacich s spr\u00e1vcom bal\u00edkov NPM, vr\u00e1tane npmjs.com. Od 4. okt\u00f3bra bude potrebn\u00e9 na pripojenie k repozit\u00e1ru, vr\u00e1tane in\u0161tal\u00e1cie bal\u00ed\u010dkov, pou\u017ei\u0165 klienta s podporou minim\u00e1lne TLS 1.2. Na samotnom GitHub boli protokoly TLS 1.0\/1.1 zastaven\u00e9 u\u017e vo febru\u00e1ri 2018. Motiv\u00e1ciou na toto rozhodnutie je starostlivos\u0165 o bezpe\u010dnos\u0165 ich slu\u017eieb a ochranu \u00fadajov pou\u017e\u00edvate\u013eov. Pod\u013ea \u00fadajov GitHubu pribli\u017ene 99% po\u017eiadaviek na repozit\u00e1r NPM u\u017e prebieha s pou\u017eit\u00edm TLS 1.2 alebo 1.3, pri\u010dom Node.js zahrnut\u00fd podporu TLS 1.2 od roku 2013 (s vydan\u00edm 0.10), tak\u017ee zmena sa dotkne len malej \u010dasti pou\u017e\u00edvate\u013eov. <\/p>\n
Nezab\u00fadajme, \u017ee protokoly TLS 1.0 a 1.1 boli ofici\u00e1lne klasifikovan\u00e9 komisiou IETF (Internet Engineering Task Force) ako zastaran\u00e9 technol\u00f3gie. \u0160pecifik\u00e1cia TLS 1.0 bola publikovan\u00e1 v janu\u00e1ri 1999. O sedem rokov nesk\u00f4r bolo vydan\u00e9 vylep\u0161enie TLS 1.1 so zlep\u0161eniami v oblasti bezpe\u010dnosti, t\u00fdkaj\u00facimi sa generovania inicializa\u010dn\u00fdch vektorov a doplnkov\u00e9ho vyplnenia. Medzi hlavn\u00e9 probl\u00e9my TLS 1.0\/1.1 patr\u00ed absencia podpory modern\u00fdch \u0161ifrovan\u00ed (napr. ECDHE a AEAD) a existencia po\u017eiadaviek na podporu star\u00fdch \u0161ifrovan\u00ed, ktor\u00fdch spo\u013eahlivos\u0165 na s\u00fa\u010dasnom stupni v\u00fdvoja v\u00fdpo\u010dtovej techniky vyvol\u00e1va pochybnosti (napr. vy\u017eaduje sa podpora TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA, pri\u010dom na overenie integrity a autentiz\u00e1ciu sa pou\u017e\u00edva MD5 a SHA-1). Podpora zastaran\u00fdch algoritmov u\u017e viedla k \u00fatokom ako ROBOT, DROWN, BEAST, Logjam a FREAK. Napriek tomu tieto probl\u00e9my neboli priamo zranite\u013enos\u0165ami protokolu a boli uzatvoren\u00e9 na \u00farovni jeho implement\u00e1ci\u00ed. V samotn\u00fdch protokoloch TLS 1.0\/1.1 neexistuj\u00fa kritick\u00e9 zranite\u013enosti, ktor\u00e9 by mohli by\u0165 vyu\u017eit\u00e9 na vykonanie praktick\u00fdch \u00fatokov.
