This article will explain in detail the differences between http and https. The quality of the article is relatively high. Therefore, Xiaobian shares it with you for reference. I hope you will have a certain understanding of relevant knowledge after reading this article.

1. Learn about http and https:

1>http:

http application layer

TCP Transport Layer

IP network layer

network interface data link layer

2>https:

http application layer

TSL or SSL security layer

TCP Transport Layer

IP network layer

network interface data link layer

2. The difference in security:

HTTPS: A security-enhanced version of the HTTP protocol that encrypts transmitted data by building an encryption layer over HTTP. The main role can be divided into two types: one is to establish an information security channel to ensure the security of data transmission; the other is to confirm the authenticity of the website.

3. Presentation: HTTPS sites will display a small green lock on the address bar to indicate that this is an encrypted and secure website. If it uses the top EV SSL Certificates certified by the world, its address bar will be highlighted in green for users to identify.

4. SEO: Baidu was unable to include HTTPS pages before 2015, but since May 2015, Baidu has been able to include HTTPS after searching for HTTPS encryption. Google has included HTTPS pages since 2014, and HTTPS pages have a higher weight than HTTP pages. From an SEO perspective, HTTPS and HTTP are not much different, and HTTPS works better.

5. Technical level: If you want to say the difference between HTTPS and HTTP, the most critical thing is still at the technical level. For example, HTTP standard port is 80, HTTPS standard port is 443;HTTP does not require certificates, HTTPS requires SSL Certificates issued by CA authorities;HTTP works at the application layer, HTTPS works at the transport layer.

What are the differences between http and https to share here, I hope the above content can be of some help to everyone, can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
