Il existe de nombreuses situations où vous devez signaler une erreur à un client qui utilise votre API.

Ce client peut être un navigateur avec un frontend, un code d'un tiers, un appareil IoT, etc.

Vous pourriez avoir besoin d'indiquer au client que :

* Le client n'a pas les privilèges suffisants pour cette opération.
* Le client n'a pas accès à cette ressource.
* L'élément auquel le client tentait d'accéder n'existe pas.
* etc.

which [TLS versions](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-tls-version/) and [cipher suites](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-cipher-suite/) to offer. A client that wants to maximize connectivity would include obsolete TLS versions and weak-by-design cipher suites. A strict client that wants to maximize security would be limited to only the latest TLS version and strongest cipher suites.

Specific security vs. connectivity decisions are implemented by [Co...
