HTTP vs HTTPS Explained
When logging in, HTTPS secures the communication between browser and server by using TLS to ensure privacy, server identity verification, and message integrity, unlike HTTP which transmits data in clear text and is vulnerable to interception and tampering.
MAIN POINTS FROM TRANSCRIPT
- HTTP transmits data in clear text, risking exposure of sensitive information.
- HTTPS uses TLS to secure HTTP messages, ensuring privacy and integrity.
- TLS handshake verifies server identity and establishes shared encryption keys.
- Certificates and key exchanges are crucial for secure HTTPS connections.
TAKEAWAYS
- HTTPS enhances HTTP by adding a secure layer via TLS, not replacing it.
- TLS handshake involves a client hello, server hello, and certificate verification.
- Certificates authenticate server identity and are signed by trusted authorities.
- Shared encryption keys protect data from being intercepted or altered in transit.
