SSL (Secure Sockets Layer) encryption is a security protocol that establishes a secure connection between a user’s browser and a website. It encrypts data transmitted between the two, ensuring confidentiality and integrity. This is especially important when sensitive information like credit card details or personal data is being shared online.
How SSL Encryption Works?
- Handshake Process: When a user accesses an SSL-enabled website, the browser requests the site’s SSL certificate.
- Verification: The website sends its SSL certificate, which includes the public key. The browser verifies the certificate against trusted Certificate Authorities (CAs) to ensure the site’s authenticity.
- Session Keys: Once verified, the browser and the server agree on a session key, which is a unique, encrypted key used for that session.
- Secure Data Transfer: All data shared between the browser and the server is now encrypted using this session key, ensuring it is protected from hackers or eavesdroppers.
SSL ensures secure communication by preventing third-party access to sensitive data and protecting websites from potential threats. You can identify SSL-protected websites by the “HTTPS” prefix and a padlock symbol in the browser’s address bar.
