If you want to change the validity of the issued certificates, you can do this by updating the column default_validity_days in the table realm_signer in the letswifi.sqlite database.

If you want to have the letswifi-portal sign the installer file, you can set signing.cert to a file containing the signing certificate and the corresponding key:

'signing.cert' => '/data/certificate.pem';

This will only work for the mobileconfig files, which are used on MacOS. On Windows, you'll use the geteduroam installer which is already signed. MacOS shows a warning if the profiles are not signed. The signing certificate can be any certificate signed by a publicly trusted authority.
