The system offers the option of using both your own certificates and Let’s Encrypt.

Own certificates

Option via p12 file:

A standard certificate, which must be in .p12 format, can be loaded from the local drive using the “Select file” button.
The certificate password is also required.
The certificate can then be installed using the “Install” button.
Select file

Option via .crt and .key file:

If there is no p12 file, the certificate and the private key plus the password can also be used directly.

Note:
Once the certificate has been successfully installed, ALL installed applications can be accessed via https.

Let’s Encrypt

An LE certificate can be installed if a domain and an e-mail are specified.
The latter is used by LE to send information as soon as the certificate has expired.

The “Provide certificate” option is required for the PW PHONE application
