Vous n’avez besoin de faire cela qu’une seule fois par projet, pas à chaque fois que vous travaillez.

Recommendations
---------------

Typically servers need a held certificate plus a chain of intermediates. Servers only need the
private key for their own certificate. The chain served by a server doesn't need the root
certificate.

* During code reviews that introduce new APIs, reviewers need to be mindful that all new properties are implemented with lazy types.
