Die folgende Anleitung beschreibt die Erstellung eines eigenen Schl<68>sselpaars.
|
|||
|
|
Dein Schl<68>sselpaar gliedert sich in zwei Teile: einen privaten Schl<68>ssel,
|
|||
|
|
den du tunlichst h<>test wie deinen Augapfel und den <20>ffentlichen Schl<68>ssel,
|
|||
|
|
der f<>r deine KorrespondenzpartnerInnen bestimmt ist.
|
|||
|
|
\end_layout
|
|||
|
|
|
|||
|
|
\begin_layout Standard
|
|||
|
|
Mit dem <20>ffentlichen Schl<68>ssel deines Adressaten verschl<68>sselst du eine
|
|||
|
|
E-Mail, welche nur der Empf<70>nger/die Empf<70>ngerin mit Hilfe seines/ihres
|
|||
|
|
privaten Schl<68>ssels wieder entschl<68>sseln kann.
|
|||
|
|
\end_layout
|
|||
|
|
|
|||
|
|
\begin_layout Standard
|
|||
|
|
Um eine verschl<68>sselte E-Mail versenden zu k<>nnen, musst du erstmal den
|
|||
|
|
<20>ffentlichen Schl<68>ssel deiner Zielperson besitzen.
|
|||
|
|
Diese wiederum ben<65>tigt deinen <20>ffentlichen Schl<68>ssel, um dir verschl<68>sselt
|
|||
|
|
antworten zu k<>nnen.

Die Passphrase sichert, dass wirklich nur du deine E-Mails ver- und entschl<68>ssel
|
|||
|
|
n kannst.
|
|||
|
|
Sie besteht idealerweise aus mehreren Gro<72>- und Kleinbuchstaben, Sonderzeichen
|
|||
|
|
und Zahlen (insgesamt mindestens f<>nfzehn Zeichen, besser w<>ren zwanzig
|
|||
|
|
oder mehr).
|
|||
|
|
Dadurch kann sie kaum von Fremden erraten werden.
|
|||
|
|
Wichtig ist nat<61>rlich, dass du sie nicht vergisst.
|
|||
|
|
Um dies zu erleichtern gibt es viele Tricks, eine leicht merkbare, aber
|
|||
|
|
sichere Passphrase zu finden:

denke an ein Lied, das du gut kennst und nimm die Anfangsbuchstaben (oder
|

|
|
die zweiten, ...

|||
|
|
\end_layout
|
|||
|
|
|
|||
|
|
\begin_layout Itemize
|
|||
|
|
denke dir einen sinnlosen Satz aus und baue ein paar Rechtschreibfehler
|
|||
|
|
und Sonderzeichen ein, z.B: Dat Koerriwurst schmoeckt n8ch #imt &nd #ucker

Die kannst du z.B.

mit Browsen im Internet verbringen.
