SSLTLSsertifikaattien

SSLTLSsertifikaattien, which translates to SSL/TLS certificates, are digital certificates that authenticate the identity of a website or server and enable encrypted communication using the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols. These certificates are crucial for establishing trust and security in online interactions.

When a user visits a website secured with an SSL/TLS certificate, their browser connects to the server. The server then presents its SSL/TLS certificate to the browser. This certificate contains information about the website's owner, the issuing Certificate Authority (CA), and the server's public key. The browser verifies the certificate's authenticity by checking if it has been issued by a trusted CA and if it hasn't expired or been revoked.

If the certificate is valid, the browser and server can then establish a secure, encrypted connection. This encryption scrambles the data exchanged between the user and the website, protecting sensitive information such as login credentials, credit card numbers, and personal details from being intercepted by malicious actors. The presence of a secure connection is typically indicated by a padlock icon in the browser's address bar and the "https://" prefix in the website's URL. SSL/TLS certificates are essential for e-commerce, online banking, and any website that handles sensitive user data.
