Es gibt zwei M<>glichkeiten wie E-Mail-Verschl<68>sselung technisch umgesetzt
|
|||
|
|
werden kann: PGP/inline und PGP/MIME.
|
|||
|
|
Nachfolgend sollen die Unterschiede zwischen beiden Varianten verdeutlicht
|
|||
|
|
werden.

|

|
|
Bei Verwendung von PGP/inline werden die Verschl<68>sselungsdaten im Textk<74>rper
|
|||
|
|
der E-Mail gespeichert.
|
|||
|
|
Dies kann oft zu Unklarheiten f<>hren, wie folgende Abbildung einer signierten

E-Mail zeigt:

Au<EFBFBD>erdem hat dieses Verfahren einige Einschr<68>nkungen, die durch PGP/MIME
|
|||
|
|
aufgehoben werden.

Hierbei handelt es sich um eine Weiterentwicklung des PGP/inline Verfahrens
|
|||
|
|
mit vielen Vorteilen:

Die Signatur ist vom E-Mail-Text getrennt und wird als Anhang mitgeschickt.
|
|||
|
|
Dies erm<72>glicht ein leichteres Lesen.

\end_layout

\begin_layout Itemize

Umlaute und andere Sonderzeichen k<>nnen ohne Probleme benutzt werden.

Allerdings solltest du beachten, dass <20>ltere Versionen von Outlook/Outlook
|
|||
|
|
Express Probleme bei der Darstellung von PGP/MIME signierten E-Mails haben.
|
|||
|
|
In diesem Fall ist es ratsam, PGP/MIME zu
