Forudsætninger

If you do not have a S/MIME key-certificate pair installed on your Nitrokey yet or if you did not installed OpenSC, please look at this page first.

You need to have OpenSC installed on your System. While GNU/Linux users usually can install OpenSC over the package manager (e.g. sudo apt update && sudo apt install opensc on Ubuntu), macOS and Windows users can download the installation files from OpenSC directly.

Bemærk

Windows-brugere med 64-bit system (standard) skal installere både 32-bit og 64-bit versionen af OpenSC!

Indstillinger i Thunderbird

Før du kan bruge Nitrokey i Thunderbird, skal du aktivere S/MIME-kryptering i kontoindstillingerne. Det kan du gøre ved at klikke på menuen og gå til »Preferences« -> »Account Settings« og klikke på »Security« i vinduet med kontoindstillinger.

Klik på »Security Devices« for at importere det rigtige PCKS11-modul. Klik på »Load« (indlæsning) i højre side. Giv nu modulet et navn (f.eks. »OpenSC Module«), og klik på »Browse« for at vælge modulets placering (se nedenfor).

On Windows the right file lays under “C:WindowsSystem32opensc-pkcs11.dll”. On macOS and GNU/Linux the file should be in “/lib/pkcs11/opensc-pkcs11.so” or “/usr/lib/pkcs11/opensc-pkcs11.so” or alike. Press “OK” twice and you are back in security section of the account settings. Now you can actually choose a certificate on the upper part of the window. You should get asked for a PIN to unlock your Nitrokey. Please type in your User PIN.

Anvendelse

Når du skriver en e-mail, kan du nu vælge at kryptere og underskrive meddelelsen.
