HTTP, HTTPS and SSL

What is HTTPS and SSL

What is HTTP protocol?

HTTP was invented alongsite HTML to create the firth interactive, text-based wed browser: the original Word Wide Web. Today the protocol remains one of the primary means of using the Internet.

HTTPS protocol and its advantages over HTT

HTTPS is HTTP with encryption. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. As a result, HTTPS is far more secure than HTTP. A website that uses HTTP has http:// in its URL, while a website that uses HTTPS has https://.

What is a SSL protocol?

SSL or Secure Sockest Layer, is a security protocol. It was invented in 1995 by Netscape, his propourse  of ensuring privacy, authentication, and data integrity in Internet communications.

Secure Sockets Layer (SSL) is a standard protocol used for the secure transmission of documents over a network. Developed by Netscape, SSL technology creates a secure link between a Web server and browser to ensure private and integral data transmission. SSL uses Transport Control Protocol (TCP) for communication.

How is work?

• In order to provide a high degree of privacy, SSL encrypts data that is transmitted across the web. This means that anyone who tries to intercept this data will only see a garbled mix of characters that’s nearly impossible to decrypt.
• SSL initiates an authentication process called a handshake between two communicating devices to ensure that both devices are really who they claim to be.
• SSL also digitally signs data in order to provide data integrity, verifying that the data is not tampered with before reaching its intended recipient.
