SSL, TLS, HTTPS Explained
ByteByteGo・5 minutes read
HTTPS is essential for securing data like passwords and credit card numbers by encrypting communication between browsers and servers through TLS. The TLS handshake process includes establishing a TCP connection, exchanging encryption keys, and agreeing on a symmetric key for safe data transmission.
Insights
- HTTPS ensures secure communication by encrypting data transmitted between browsers and servers, safeguarding sensitive information from potential interception, such as passwords and credit card details.
- The TLS handshake process, integral to HTTPS, includes establishing a secure connection via TCP, exchanging encryption keys using asymmetric encryption, and agreeing on a symmetric encryption key for protected data transmission, highlighting the complexity and robust security measures involved in HTTPS implementation.

Importance of HTTPS for Secure Communication
- HTTPS is crucial for secure communication between browsers and servers, preventing interception of sensitive data like passwords and credit card numbers.
- HTTPS is an extension of HTTP, with data sent in encrypted form using TLS (Transport Layer Security).
- The TLS handshake involves steps like the browser establishing a TCP connection, exchanging client hello and server hello messages, sharing encryption keys using asymmetric encryption, and agreeing on a symmetric encryption key for secure data transmission.
