# How To Add Certificates

## Let’s Encrypt App

Univention offers an easy way to get secure certificates with their Let’s Encrypt app. To install it:

- In the Univention Appcenter, click on Software and search for Let’s Encrypt.
- Go to the App Settings and generate an certificate by entering your domain name(s).
- After the certificate is generated, restart the web server (or the appliance).

## Import your own certificates

If you want to use your own SSL certificates for the appliance, you have to follow these three steps:

1. Create the certificates and deposit them on your appliance.
2. Connect to your appliance either directly on the command line of your virtual machine or via ssh connection to your appliance.
3. Execute the following commands:

    ucr set apache2/ssl/certificate="/etc/myssl/cert.pem"
    ucr set apache2/ssl/key="/etc/myssl/private.key"

Note

Remember to adjust the path and filename to match your certificate.

Once you’ve completed these steps, restart Apache using the following command:

    service apache2 restart

Now your certificates will be used to access your appliance.

If you want to limit the access to your server exclusively to HTTPS, use this command:

    ucr set apache2/force_https=yes
