What Are HTTP, HTTPS, SSL, and TLS?

TL;DR

HTTP transmits data in clear text, which leaves it vulnerable to hackers, while HTTPS encrypts this data to ensure secure online communication. SSL and TLS are protocols that enable HTTPS by authenticating websites and encrypting data, making personal information protected during transmission.

Transcript

Hello everyone in this video we're going to talk  about HTTP, secure HTTP, and SSL. Now HTTP stands   for Hypertext Transfer Protocol. Now this is  probably the most widely used protocol in the   world today. HTTP is the protocol that is used  for viewing web pages on the internet. So when   you type in a web address, like google.com, you'll  not... Read More

Key Insights

• 💁 HTTP is widely used for web browsing but transmits information in clear text, making it vulnerable to hackers.
• 💁 HTTPS encrypts data transmitted over the internet, ensuring the security and privacy of sensitive information.
• ❓ SSL and TLS are protocols used by secure HTTP to authenticate websites, encrypt data, and establish a secure connection.

Questions & Answers

Q: What is the difference between HTTP and HTTPS?

HTTP transmits data in clear text, making it vulnerable to hackers, while HTTPS encrypts data to ensure secure transmission over the internet.

Q: How does HTTPS protect sensitive information?

HTTPS encrypts sensitive information, such as passwords and credit card numbers, during transmission, making it unreadable to hackers, thus ensuring data security.

Q: What is SSL and how does it work?

SSL (Secure Sockets Layer) is a protocol used to ensure security on the internet. It uses public key encryption to authenticate websites and encrypt data, protecting it from unauthorized access.

Q: Why are websites using secure HTTP by default?

Websites are increasingly using secure HTTP by default due to Google's policy of flagging non-SSL protected sites as "not secure." This encourages website owners to prioritize data security to maintain their search rankings.

Key Insights:

• HTTP is widely used for web browsing but transmits information in clear text, making it vulnerable to hackers.
• HTTPS encrypts data transmitted over the internet, ensuring the security and privacy of sensitive information.
• SSL and TLS are protocols used by secure HTTP to authenticate websites, encrypt data, and establish a secure connection.
• Secure HTTP is becoming the standard for websites, driven by search engine policies and the increasing need for data security.

Summary & Key Takeaways

• HTTP is the most widely used protocol for viewing web pages on the internet, but it transmits all information in clear text, making it vulnerable to hackers.

• HTTPS, or Secure HTTP, encrypts data transferred over the internet, making it impossible to read and ensuring secure transmission.

• SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols used by secure HTTP to authenticate websites, encrypt data, and ensure security.
