I den foresl\u00e5ede version er der p\u00e5begyndt \u00e6ndringer, der g\u00e5r forud for den fremtidige oph\u00e6velse af underst\u00f8ttelsen af n\u00f8gler baseret p\u00e5 DSA-algoritmen. I OpenSSH 9.7 er der tilf\u00f8jet en mulighed for at deaktivere DSA ved kompilering, men standardbygningen bevarer stadig DSA-underst\u00f8ttelsen. I n\u00e6ste udgave, der er planlagt til juni, vil byggeindstillingerne \u00e6ndres til at deaktivere DSA som standard, og i begyndelsen af 2025 vil DSA-implementeringen blive fjernet fra kodebasen.       <\/p>\n<p>Som standard blev brugen af DSA-n\u00f8gler stoppet allerede i 2015, men koden til DSA-underst\u00f8ttelse blev stadig inkluderet som standard og tillod genaktivering af DSA via indstillinger. Det er bem\u00e6rkelsesv\u00e6rdigt, at DSA-algoritmen er den eneste, der er obligatorisk at implementere i SSHv2-protokollen. Dette krav blev tilf\u00f8jet, da alle alternative algoritmer var underlagt patenter p\u00e5 tidspunktet for oprettelsen og godkendelsen af SSHv2-protokollen. Siden da har situationen \u00e6ndret sig, patenterne relateret til RSA er udl\u00f8bet, og algoritmen ECDSA, som er betydeligt mere effektiv og sikker end DSA, er blevet tilf\u00f8jet, ligesom EdDSA, som er mere sikker og hurtigere end ECDSA.     <\/p>\n<p>Den eneste faktor for fortsat underst\u00f8ttelse af DSA har v\u00e6ret bevarelsen af kompatibilitet med for\u00e6ldede enheder. I den nuv\u00e6rende situation retf\u00e6rdigg\u00f8r omkostningerne ved fortsat vedligeholdelse af den usikre DSA-algoritme ikke sig selv, og dens fjernelse vil fremme oph\u00e6velsen af DSA-underst\u00f8ttelsen i andre SSH-implementationer og kryptografiske biblioteker.       <\/p>\n<p>Udover \u00e6ndringer relateret til DSA introducerer den nye version en ny type timeouts i ssh og sshd, som aktiveres ved at angive v\u00e6rdien \"global\" i direktivet ChannelTimeout. I denne nye tilstand overv\u00e5ger OpenSSH alle \u00e5bne kanaler og lukker dem samtidigt, hvis der ikke har v\u00e6ret trafik i nogen af dem inden for den angivne tidsramme. For eksempel, n\u00e5r der er \u00e5bne kanaler til SSH-session og x11-omdirigering p\u00e5 serveren, g\u00f8r den nye tilstand det muligt at lukke begge kanaler samtidigt, hvis de er inaktive, i stedet for at spore timeouts for hver kanal hver for sig. Derudover bem\u00e6rkes der en betydelig forbedring i kompatibilitetstestningen med PuTTY-projektet.<br \/>\n<br \/>Kilde: <a content=\"nofollow\" rel=\"nofollow\"
