SSL (Secure Sockets Layer) is a security protocol that establishes an encrypted link between a web server and a browser. HTTPS (HyperText Transfer Protocol Secure) is an extension of HTTP that uses SSL or its successor TLS (Transport Layer Security) to encrypt data transmitted between the web server and the browser, ensuring secure communication.
HTTPS uses SSL or TLS to provide a secure connection, while SSL itself is the underlying technology that enables encryption and security for data transmission. Essentially, HTTPS is HTTP with SSL/TLS encryption.
Not all HTTPS connections use SSL. Modern HTTPS connections typically use TLS, which is the successor to SSL. SSL is considered outdated and less secure compared to TLS.
HTTPS (HyperText Transfer Protocol Secure) and S-HTTP (Secure HyperText Transfer Protocol) are both protocols used to secure communication over the internet. HTTPS secures the entire session using SSL/TLS encryption, while S-HTTP secures individual messages rather than the entire session. S-HTTP is less commonly used compared to HTTPS.
Yes, you need SSL or TLS for HTTPS. HTTPS relies on SSL/TLS to encrypt data and secure the connection between the web server and the browser.
