Register the Smartcard

The final thing to do now, is to register the smartcard and the key to gpg.

The easiest way for me, since I have set the URL of public key attribute on my YubiKey, is to

Edit the card
Terminal window
```
gpg --card-edit
```
Fetch the public key from the URL
gpg/card>
```
fetch
```
Quit out of the prompt
gpg/card>
```
quit
```
Edit the key / key associated with your e-mail
Terminal window
```
gpg --edit-key info@dustvoice.de
```
Give the key ultimate (5) trust, as you should be the key owner, and confirm it with y
gpg>
```
trust
5
y
```
Save the changes and quit the prompt.
gpg>
```
save
```
