What are SSL certificates and why do you need one?
SSL certificates are small data files that digitally bind a cryptographic key to an organization's details.

Basically, it provides authentication for a website and enables encrypted communication between the site and its visitors, which is crucial for protecting sensitive information such as credit card numbers, passwords, and personal data.

SSL certificates work by using a combination of public and private keys to encrypt and decrypt data. When a visitor accesses a website with an SSL certificate, their browser sends a request to the server. The server then sends back a copy of its SSL certificate. The browser checks to make sure that the certificate is valid and then uses the public key in the certificate to encrypt a session key.
