I den f\u00f6reslagna versionen har f\u00f6r\u00e4ndringar p\u00e5b\u00f6rjats som f\u00f6reg\u00e5r det kommande avskaffandet av st\u00f6d f\u00f6r nycklar baserade p\u00e5 DSA-algoritmen. OpenSSH 9.7 tillhandah\u00e5ller en option f\u00f6r att avaktivera DSA vid kompilering, men standardbygget beh\u00e5ller fortfarande st\u00f6d f\u00f6r DSA. I n\u00e4sta version, som \u00e4r planerad till juni, kommer byggrutinen att \u00e4ndras till att avaktivera DSA som standard, och i b\u00f6rjan av 2025 kommer implementeringen av DSA att tas bort fr\u00e5n koden.       <\/p>\n<p>Som standard avskaffades anv\u00e4ndningen av DSA-nycklar redan 2015, men koden f\u00f6r att st\u00f6dja DSA kompilerades fortfarande som standard och m\u00f6jliggjorde att DSA kunde \u00e5terinf\u00f6ras genom inst\u00e4llningar. Det \u00e4r anm\u00e4rkningsv\u00e4rt att DSA-algoritmen \u00e4r den enda som \u00e4r obligatorisk att implementera i protokollet SSHv2. Ett s\u00e5dant krav inf\u00f6rdes eftersom alla alternativa algoritmer omfattades av patent n\u00e4r protokollet SSHv2 skapades och godk\u00e4ndes. Sedan dess har situationen f\u00f6r\u00e4ndrats, de patent som r\u00f6r RSA har upph\u00f6rt, ECDSA-algoritmen har lagts till, vilket \u00f6vertr\u00e4ffar DSA avsev\u00e4rt n\u00e4r det g\u00e4ller prestanda och s\u00e4kerhet, samt EdDSA, som \u00e4r s\u00e4krare och snabbare \u00e4n ECDSA.     <\/p>\n<p>Den enda faktorn f\u00f6r fortsatt st\u00f6d av DSA var att uppr\u00e4tth\u00e5lla kompatibilitet med f\u00f6r\u00e5ldrad utrustning. I dagens l\u00e4ge motiverar kostnaderna f\u00f6r att forts\u00e4tta underh\u00e5lla den os\u00e4kra DSA-algoritmen sig inte, och dess borttagande kommer att stimulera ett avskaffande av DSA-st\u00f6d i andra SSH-implementationer och kryptografiska bibliotek.       <\/p>\n<p>F\u00f6rutom \u00e4ndringarna relaterade till DSA, introduceras en ny typ av timeout f\u00f6r ssh och sshd i den nya versionen, som aktiveras genom att ange v\u00e4rdet \"global\" i direktivet ChannelTimeout. I det nya l\u00e4get sp\u00e5rar OpenSSH alla \u00f6ppna kanaler och st\u00e4nger dem samtidigt om det under angiven tidsperiod inte har f\u00f6rekommit n\u00e5gon trafik i dem. Till exempel, n\u00e4r det finns \u00f6ppna kanaler f\u00f6r SSH-session och omdirigering av x11 till en v\u00e4rd, m\u00f6jligg\u00f6r det nya l\u00e4get att st\u00e4nga b\u00e5da kanalerna samtidigt om de \u00e4r inaktiva, ist\u00e4llet f\u00f6r att sp\u00e5ra timeouter separat f\u00f6r varje kanal. Bland \u00e4ndringarna finns \u00e4ven en avsev\u00e4rd f\u00f6rb\u00e4ttring av kompatibilitetstesterna med PuTTY-projektet.<br \/>\n<br \/>K\u00e4lla: <a content=\"nofollow\" rel=\"nofollow\"
