The use of public key in service configuration is not related to a client
web browser connecting to your CAS server over https. CAS requires the use
public/private keys when releasing sensitive information as part of the
returned attributes. The proxy service is one such case due to the option
to return the PGT-IOU as an attribute rather than requiring the target
application to provide a pgtURL. This is documented here:

https://apereo.github.io/cas/5.3.x/installation/Configuring-Proxy-Authentication.html#pgt-in-validation-response

You should only implement this if your use case fits the description in the
first paragraph. Knowing if you are using a pgtURL callback or attribute
release will help to answer other questions.
