-#+TITLE:     Certifikat
-#+SETUPFILE: includes/level-0.org

-Fripost använder säkra anslutningar med certifikat från bland annat [[https://cacert.org][CAcert]]. Det
-är inte alla webbläsare som automatiskt litar på certifikat signerade av CAcert,
-och därför måste dessa webbläsare förses med [[http://www.cacert.org/index.php?id=3][CAcerts root-certifikat]].
-
-De flesta webbläsare har guider för hur man förser dem med certifikat. Artikeln
-"[[http://wiki.cacert.org/FAQ/ImportRootCert][How can I trust CAcert's root certificate?]]" beskriver också utförligt hur man
-gör.
-
-Det är bra att jämföra certifikatens fingeravtryck med några man får från en
-pålitlig källa.
-
-Detta är fingeravtryck till certificat som Fripost använder
