GitHub teatas, et teeb teenuses muudatusi, mis on seotud Git-protokolli kaitse tugevdamisega, mida kasutatakse git push ja git pull toimingute tegemisel SSH v\u00f5i skeemi «git:\/\/» kaudu (HTTPS kaudu toimingud ei m\u00f5juta). Muudatuste j\u00f5ustumisel on GitHubiga SSH-i kaudu \u00fchenduse loomine vajalik v\u00e4hemalt OpenSSH versioon 7.2 (v\u00e4lja antud 2016. aastal) v\u00f5i PuTTY versioon 0.75 (v\u00e4lja antud sel aastal mai kuus). N\u00e4iteks on CentOS 6 ja Ubuntu 14.04 koos SSH-klientidega, mille tugi on juba l\u00f5petatud, \u00fchilduvus rikkuv. <\/p>\n

Muudatused seisnevad selles, et l\u00f5petatakse ei-kr\u00fcpteeritud \u00fchenduste toetamist Gitiga (kasutades «git:\/\/») ning suurendatakse n\u00f5udmisi SSH-v\u00f5tmete osas, mida kasutatakse GitHubiga \u00fchenduse loomiseks. GitHub l\u00f5petab k\u00f5igi DSA-v\u00f5tmete ja vananenud SSH-algoritmide, nagu CBC \u0161ifrid (aes256-cbc, aes192-cbc, aes128-cbc) ning HMAC-SHA-1 toetamist. Lisaks rakendatakse uusi n\u00f5udeid uutele RSA-v\u00f5tmetele (SHA-1 kasutamine on keelatud) ning toetatakse ECDSA ja Ed25519 hostiv\u00f5tmeid. <\/p>\n

Muutused viiakse ellu j\u00e4rk-j\u00e4rgult. 14. septembril genereeritakse uued ECDSA ja Ed25519 hostiv\u00f5tmed. 2. novembril l\u00f5petatakse RSA v\u00f5tmete toetamine, mis p\u00f5hinevad SHA-1-l (varasemad genereeritud v\u00f5tmed j\u00e4tkavad t\u00f6\u00f6d). 16. novembril l\u00f5petatakse DSA algoritmiga hostiv\u00f5tmete toetamine. 11. jaanuaril 2022 katseprojektina l\u00f5petatakse ajutiselt vanade SSH algoritmide ja v\u00f5imaluse puhul, kus ei kasutata kr\u00fcpteerimist, toetamista. 15. m\u00e4rtsil l\u00f5petatakse vanade algoritmide l\u00f5plik toetamine. <\/p>\n

Lisaks v\u00f5ib m\u00e4rkida, et OpenSSH koodibaasi on lisatud muudatus, mis vaikimisi keelab SHA-1 («ssh-rsa») alusel RSA v\u00f5tmete t\u00f6\u00f6tlemise. SHA-256 ja SHA-512 (rsa-sha2-256\/512) alusel RSA v\u00f5tmete tugi j\u00e4\u00e4b muutumatuks. «ssh-rsa» v\u00f5tmete toe l\u00f5petamine on tingitud suurenenud efektiivsusest konflikti r\u00fcnnakute puhul, mille maksumus on hinnanguliselt umbes 50 000 dollarit. oma s\u00fcsteemides «ssh-rsa» kasutamise kontrollimiseks, proovige ssh abil \u00fchendust luua, kasutades valikut «-oHostKeyAlgorithms=-ssh-rsa».
