@subsection Installation on Vista |

|
|
27 |
|
Because of the nature of the plugin, it contains a lot of tricks |
28 |
|
for the Express integration, it cannot be guranteed, that it works |
29 |
|
on Vista in general or the Outlook Express version that comes |
30 |
|
with Vista. Feedback on the use with Vista is welcome but the |
31 |
|
adjustment, if possible at all will take a lot of time. |

@subsection Sign and Encrypt a message |
83 |
|
To sign and encrypt a message, you have to check both toolbar |
84 |
|
buttons ("Sign" and "Encrypt"). The procedure is the same as |
85 |
|
in encrypt-only when one or more email addresses couldn't be |
86 |
|
mapped. Then the default key is used to sign the plaintext |
87 |
|
before it is encrypted with the selected recipients. |

@subsection Reply to an encrypted message |
102 |
|
Newer versions of the plug-in provide a feature to decrypt the |
103 |
|
message before the text is used in the reply mail. As a result, |
104 |
|
the reply message will contain the plain text instead of the encrypted |
105 |
|
GPG armored message. |
106 |
|
This feature is automatically used whenever the user clicks on "Reply" |
107 |
|
or "Reply All" in the Outlook main window. But only in the case, the |
108 |
|
mail is actually encrypted. Optionally the plug-in will ask for a |
109 |
|
key passphrase. |

If you manually installed GPG and GPGoe, please make sure that |
117 |
|
you installed GPG at a standard place or create at least the gpgBinary |
118 |

registry entry. This is not needed if you use an automatic installer |

Due to the fact the plug-in uses the clipboard for data transfer, |
123 |
|
the clipboard itself can be only of limited use to copy/paste messages |
124 |
|
into the mailer window or elsewhere. Newer versions of the plug-in |
125 |
|
save the original clipboard text before encryption/signing and the |
126 |
|
text is restored after the GPG operation ends. |
