Krypter med DanIDs “Digital Signatur” i Evolution

Er du bruger af Evolution og har behov for at sende en krypteret mail med DanIDs "Digital Signatur", skal du først have fat i kontaktpersonens certifikat. Dette finder du på DanIDs Certificeringscenter, såfremt personen har valgt at være listet her. Når du har fundet det rette certifikat klikke du på download, hvorefter du kan gemme en .cer fil.

I Evolution vælger du Rediger -> Indstillinger (eller Shift-Ctrl-S) -> Certifikater -> Kontaktpersoners certifikater -> Importer hvorefter du får mulighed for at importere den hentede .cer fil.

Du skal naturligvis have din egen private signaturfil i Evolution.

Re-install / upgrade to Ubuntu 9.10 and keep encrypted data from previous version

When Ubuntu first started with encrypted hard drive support, I made a LVM system inside the encrypted system. I do not like to upgrade Ubuntu from one version to another, and I do not want to copy all my data for each installation. My LVM system therefore have root, swap and home, so that home can survive the re-installation.

Unfortunately, the installer (the alternative one) do not recognise the encrypted hard drive, and is therefore not able to use it. This little guide helps you to reuse your LVM layout - and your data!

NB: Use this guide at your own risk!
