Gaim/Pidgin bietet <20>ber ein Plugin die M<>glichkeit, die sichere Verschl<68>sselung
|
|||
|
|
von Off-the-Record zu verwenden.
|
|||
|
|
Dieses kann man einfach hier unter "OTR plugin for gaim" f<>r die entsprechende
|
|||
|
|
Linux-Distribution oder f<>r Windows herunterladen.
|
|||
|
|
Das Einbinden des Plugins in die aktuelle Gaim2 Beta3 Testversion funktioniert
|
|||
|
|
anscheinend leider noch nicht richtig.
|
|||
|
|
Nach einem Neustart Gaims sollte man das Plugin dann in den Einstellungen
|
|||
|
|
unter "Plugins" mit einem H<>ckchen unter "Laden" aktivieren k<>nnen.
|
|||
|
|
Theoretisch sind nun, um die Verschl<68>sselung von OTR zu nutzen, keine weiteren
|
|||
|
|
Einstellungen n<>tig.
|
|||
|
|
Praktisch gesehen sollte man sich aber noch einen Fingerprint erstellen.

Unter "Config" kann man sich nun seinen eigenen Fingerprint erstellen, damit
|
|||
|
|
die anderen Kontakte sichergehen k<>nnen, dass sie mit dir und keinem anderen
|
|||
|
|
sprechen.
|
|||
|
|
Hierf<72>r muss man einfach unter "Key for account" den gew<65>nschten Accound
|
|||
|
|
ausw<73>hlen und mit "Generate" einen Fingerprint generieren.
|
|||
|
|
Dies macht man am besten nacheinander f<>r alle Accounts.

Unter "Known fingerprints" in den Gaimeinstellungen kann man sehen, von

|

wem man schon einen "fingerprint" erhalten hat.
|

|

Diese Fingerprints sind daf<61>r da, um sicherzugehen, dass man auch mit demjenige

|
n spricht, mit dem man sprechen wollte.

Siehe dazu das zweite Grundprinzip von OTR.
