HTTPS protocol detailed (i): HTTPS basics

Reproduced

----------------------------------------------------------------------------
HTTPS Basics: HTTPS (Secure hypertext Transfer Protocol) Secure Hypertext Transfer Protocol is a secure communication channel that is based on HTTP development for exchanging information between client computers and servers.    It uses Secure Sockets Layer (SSL) for information exchange, which is simply a secure version of HTTP and an HTTP protocol that uses TLS/SSL encryption. The HTTP protocol transmits the information in clear text, there is the risk of information eavesdropping, information tampering and information hijacking, and the protocol Tls/ssl has the functions of authentication, information encryption and integrality checking, which can avoid such problems.
TLS/SSL Full Name Secure Transport Layer protocol Transport Layer Security, which is between TCP and HTTP, does not affect the original TCP protocol and HTTP protocol, so using HTTPS basically does not require much modification of the HTTP page.

What is the difference between HTTPS and HTTP?

First, what is HTTPS
HTTPS is a secure version of the HTTP protocol that establishes an SSL encryption layer on HTTP and encrypts the transmitted data. The main functions of HTTPS are:
(1) Encrypt the data and establish an information security channel to ensure the data security in the transmission process;
(2) The real identity authentication of the website server.
Second, what is HTTP
HTTP is the most widely used network protocol on the Internet and is a standard (TCP) for client and server-side requests and responses for transmitting hypertext to a local browser from a WWW server. HTTP is the use of plaintext data transmission, it is very easy to be stolen and tamper with illegal elements.
Iii. What is the difference between HTTPS and HTTP?
1, HTTPS is encrypted transmission protocol, HTTP is the name of the text transmission protocol;
2, HTTPS need to use the SSL certificate, and HTTP is not used;
3, HTTPS more secure than HTTP, more friendly to search engines, conducive to SEO
4, HTTPS standard port 443,http standard port 80;
5, HTTPS based on the Transport layer, HTTP based on the application layer;
6, HTTPS in the browser display green Security lock, HTTP is not displayed;
In general, HTTPS is more secure than HTTP and can effectively protect the privacy information of website users, which is why there are more and more https websites now. If you do not want your site because of data leakage on the headlines, go to apply for an SSL certificate for their website to implement HTTPS encryption!
