Pr\u00e6senteret<\/a><\/noindex> udgave af messenger Delta Chat 1.0<\/a><\/noindex> til Android-platformen (den seneste version til desktop er 0.901<\/a><\/noindex>, og for iOS \u2014 0.960<\/a><\/noindex>). Projektet Delta Chat er bem\u00e6rkelsesv\u00e6rdigt for at bruge almindelig e-mail som transport til \u00f8jeblikkelige meddelelser (chat-over-email, en specialiseret e-mailklient, der fungerer som messenger). Koden til applikationerne distribueres<\/a><\/noindex> er under GPLv3 licens, mens den grundl\u00e6ggende biblioteker er tilg\u00e6ngelig under MPL 2.0 (Mozilla Public License). Udgivelsen tilg\u00e6ngelig<\/a><\/noindex> er i Google Play.<\/p>\n

Delta Chat bruger ikke egne servere og kan fungere gennem n\u00e6sten enhver e-mailserver, der underst\u00f8tter SMTP og IMAP (til hurtig registrering af nye meddelelser anvendes en teknik Push-IMAP<\/a><\/noindex>). Der underst\u00f8ttes kryptering ved hj\u00e6lp af OpenPGP og standarden Autocrypt<\/a><\/noindex> til nem automatisk ops\u00e6tning og deling af n\u00f8gler uden brug af n\u00f8gle-servere (n\u00f8glen overf\u00f8res automatisk i den f\u00f8rste sendte besked). Implementeringen af end-to-end kryptering er baseret p\u00e5 koden rPGP<\/a><\/noindex>, som i \u00e5r har gennemg\u00e5et en uafh\u00e6ngig sikkerhedsrevision. Trafikken krypteres ved hj\u00e6lp af TLS i implementeringen af standard systembiblioteker.<\/p>\n

Delta Chat er helt under brugers kontrol og knyttes ikke til centraliserede tjenester. Registrering i nye tjenester er ikke n\u00f8dvendig, og eksisterende e-mail kan bruges som identifikator. Hvis modtageren ikke bruger Delta Chat, kan de l\u00e6se meddelelsen som et almindeligt brev. Bek\u00e6mpelse af spam sker ved at filtrere meddelelser fra ukendte brugere (som standard vises kun meddelelser fra brugere i addressbogen og dem, der tidligere har f\u00e5et sendt meddelelser, samt svar p\u00e5 egne meddelelser). Det er muligt at vise vedh\u00e6ftede filer og billeder samt videoer. <\/p>\n

Underst\u00f8ttelse af oprettelse af gruppechats, hvor flere deltagere kan kommunikere. Der er mulighed for at knytte en verificerbar deltagerliste til gruppen, som forhindrer uvedkommende i at l\u00e6se beskederne (deltagere verificeres via kryptografisk signatur, og beskeder krypteres med slut-til-slut kryptering). Tilslutning til verificerede grupper sker ved at sende en invitation med en QR-kode. Verificerede chats har i \u00f8jeblikket status som en eksperimentel funktion, men deres st\u00f8tte forventes at blive stabiliseret i starten af 2020 efter afslutning af sikkerhedsrevisionen.<\/p>\n

Kernen i messenger er udviklet separat som et bibliotek og kan bruges til at skrive nye klienter og bots. Den aktuelle version af det grundl\u00e6ggende bibliotek er skrevet<\/a><\/noindex> i Rust (den gamle version var skrevet<\/a><\/noindex> i C). Der er bindinger til Python, Node.js og Java. I udvikling<\/a><\/noindex> er der uofficielle bindinger til Go. <\/p>\n

Sammenlignet med den tidligere version 0.510.1 er den grundl\u00e6ggende bibliotek omskrevet fra C til Rust uden brug af usikker kode. Underst\u00f8ttelse af avatarer er tilf\u00f8jet samt muligheden for at bruge Delta Chat som e-mailklient til at l\u00e6se almindelige breve, der ikke er sendt via Delta Chat.<\/p>\n
