Conform standardelor actuale, cheile DSA nu ofer\u0103 un nivel adecvat de protec\u021bie, folosind o dimensiune a cheii private de doar 160 de bi\u021bi \u0219i un hash SHA1, ceea ce corespunde, din punct de vedere al nivelului de securitate, unei chei simetrice de aproximativ 80 de bi\u021bi.     <\/p>\n<p>\u00cen mod implicit, utilizarea cheilor DSA a fost oprit\u0103 \u00een 2015, dar suportul pentru DSA a fost p\u0103strat ca op\u021biune, deoarece acest algoritm este singurul care trebuie implementat \u00een protocolul SSHv2. Aceast\u0103 cerin\u021b\u0103 a fost ad\u0103ugat\u0103 deoarece, la momentul cre\u0103rii \u0219i aprob\u0103rii protocolului SSHv2, toate algoritmii alternativi erau sub inciden\u021ba brevetelor. \u00centre timp, situa\u021bia s-a schimbat, brevetele legate de RSA au expirat, algoritmul ECDSA a fost ad\u0103ugat, dep\u0103\u0219ind semnificativ DSA din punct de vedere al performan\u021bei \u0219i securit\u0103\u021bii, precum \u0219i EdDSA, care este mai sigur \u0219i mai rapid dec\u00e2t ECDSA. Singurul factor care a men\u021binut suportul pentru DSA a fost p\u0103strarea compatibilit\u0103\u021bii cu dispozitivele \u00eenvechite.     <\/p>\n<p>Evalu\u00e2nd situa\u021bia din prezent, dezvoltatorii OpenSSH au concluzionat c\u0103 costurile pentru continuarea \u00eentre\u021binerii algoritmului DSA nesigur nu justific\u0103 eforturile \u0219i eliminarea acestuia va stimula oprirea suportului DSA \u00een alte implement\u0103ri SSH \u0219i biblioteci criptografice. \u00cen versiunea planificat\u0103 pentru aprilie, OpenSSH inten\u021bioneaz\u0103 s\u0103 p\u0103streze o compilare cu DSA, dar s\u0103 ofere op\u021biunea de a dezactiva DSA \u00een timpul compil\u0103rii. \u00cen versiunea din iunie a OpenSSH, DSA va fi dezactivat implicit la compilare, iar la \u00eenceputul anului 2025, implementarea DSA va fi eliminat\u0103 din baza de cod.       <\/p>\n<p>Utilizatorii care au nevoie de suport DSA de partea clientului pot folosi versiuni alternative ale vechilor ramuri OpenSSH, cum ar fi pachetul furnizat \u00een Debian &#171;openssh-client-ssh1&#187;, care se bazeaz\u0103 pe OpenSSH 7.5 \u0219i este destinat conect\u0103rii la serverele SSH folosind protocolul
