szervertanúsítvánnyal

A "szervertanúsítvány" in Hungarian translates to "server certificate" in English. It is a type of digital certificate used to secure communication between a web server and a client, most commonly a web browser. These certificates are issued by trusted Certificate Authorities (CAs) and are a fundamental component of secure web browsing, enabling the HTTPS protocol.

The primary purpose of a server certificate is to authenticate the identity of the web server. When a browser connects to a server that uses HTTPS, it requests the server's certificate. The browser then verifies the certificate's validity by checking if it was issued by a trusted CA and if it hasn't expired or been revoked. This process helps ensure that the user is communicating with the legitimate website they intended to visit and not an imposter.

Beyond authentication, server certificates also enable encryption. The certificate contains the server's public key, which the browser uses to establish a secure, encrypted connection with the server. This encryption scrambles the data exchanged between the client and server, protecting sensitive information like login credentials, credit card numbers, and personal data from being intercepted by attackers. The padlock icon typically seen in web browsers is a visual indicator that a secure connection, facilitated by a server certificate, is active.
