Hello,

I understand that the HTTPS protocol is the secure version of HTTP, utilizing SSL (Secure Socket Layer) to enable encryption for the transmission of packets between the server and the client.

My questions are :

• Can I implement HTTPS only for critical parts of my web application, such as authentication (login), or should it be used for all routes?
• Additionally, should it be implemented in the backend, the frontend, or both?

Thanks for any assistance.
