An SSL certificate ensures authenticity by verifying that the website or server being accessed is actually the website or server it claims to be. This is done through a process called authentication, which validates the identity of the website owner or organization behind the website.
When a website owner obtains an SSL certificate from a trusted Certificate Authority (CA), they must provide proof of their identity and ownership of the domain. The CA then verifies this information and issues an SSL certificate that contains the website owner’s information, including their name, address, and other identifying details.
When a user visits a website with an SSL certificate, their web browser checks if the SSL certificate is valid and issued by a trusted CA. If the SSL certificate is valid, the browser then uses the website’s public key to establish a secure connection with the website and encrypt any data that is exchanged.
By using SSL certificates, websites can provide assurance to users that the website they are accessing is legitimate and secure, and that any data they enter or transmit is encrypted and protected from unauthorized access.
