In this issue, the editor will bring you about the SSL certificate how to turn HTTP into HTTPS. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Abstract

What is the role of changing from HTTP to HTTPS,SSL certificate?

In recent years, "Internet +" as the mainstream direction of economic development, various industries have carried out integration with the Internet, and actively establish online brands and business. Half of the "four new inventions of China" that have appeared on the Internet are closely related to the Internet, namely "online payment" and "online shopping".

But the ensuing network security problems are also increasingly exposed to businesses and users-the two are connected by network signals, but in reality they may be thousands of miles apart, how to confirm each other's identity?

As early as 1994, Netscape developed a network security protocol, the secure Sockets layer (SSL,Secure Socket Layer) protocol, to meet the need of network authentication.

When SSL is not used, the application data in the application layer interacts with the transport layer through TCP sockets. After using SSL, because SSL makes TCP's services more secure, it looks like SSL should be the transport layer protocol.

In practice, however, applications that need to use secure transport, such as HTTP, host SSL at the application layer, causing the application layer to expand.

In the expanded application layer, there is an SSL sublayer under the application, and there is a SSL socket between the application and the SSL sublayer, which is similar to the TCP socket and is the application programming interface API of the application and SSL sublayer.

HTTP is the most frequently used SSL in the application layer, but SSL is not only used for HTTP, but also can be used for any application layer protocol, such as IMAP mail access authentication and data encryption.

The application HTTP encrypts the entire web page by calling SSL, and the http in the URL bar becomes https, where the s added by https represents security, indicating that the HTTP protocol that provides security services is now used. TCP's HTTPS port number is 443 instead of the usual port number 80.

What is the role of changing from HTTP to HTTPS,SSL certificate?

The SSL certificate mainly serves HTTPS. After the certificate is deployed, the link to the website changes from HTTP to HTTPS.

Mainly used for sending secure e-mail, visiting secure sites, online bidding and bidding, online signing, online ordering, online office, online payment, online tax payment and online shopping and other secure online electronic trading activities.

SSL certificate content implements two basic functions

1. Data transmission encryption

Our usual Internet access and browsing are based on the standard TCP/IP protocol, and the content is transmitted on the network in the form of data packets.

Because the contents of the packet are not encrypted, anyone who intercepts the packet can obtain the content. Then if the user name, password or other personal information is transmitted in the data packet, it is easy to be stolen by others.

SSL can establish an encrypted channel between the client (such as browser) and the server used by the user. All data transmitted on the network will be encrypted first, and then decrypted when it is transmitted to the destination, so that even if the data packet is intercepted during transmission, it is difficult to crack its contents.

two。 Server information certificate

At present, counterfeit websites have become a serious threat to the use of the Internet. Counterfeiters can make an interface exactly the same as the real website, and use similar domain names to guide users to visit.

If the user does not pay attention, it is easy to be fooled. Once the information such as account number and password is entered in the use of the counterfeit website, it will be recorded by the counterfeit website, and then be used falsely, threatening the security of the user's account.

SSL server certificate can effectively prove the true information of the website and the legitimacy of the use of domain names, so that users can easily identify real websites and counterfeit websites.

When applying for a SSL certificate, the identity of the applicant will be confirmed by strict examination. When users visit the website, they can see the contents of the certificate, including the real domain name of the website, the owner of the website, the certificate issuing organization and other information. The browser will also give the corresponding security logo, so that visitors can rest assured to use.

1.EV SSL Certificate-enhanced SSL Certificate

Manifestation: the green address bar shows the company name + security lock + HTTPS, which is suitable for financial securities, banks, third-party payment, online shopping malls, etc., with emphasis on website security and brand trusted image of the website, involving transaction payment, customer privacy information and account password transmission, it is recommended to choose the EV SSL certificate showing the green address bar, which is more worthy of user trust.

2.OV SSL Certificate-Enterprise SSL Certificate

Presentation: the address bar shows security lock + HTTPS and the details of the SSL certificate contain enterprise information, which cannot be imitated. It is suitable for corporate websites, business websites, securities, financial institutions, and so on. The certificate authority examines the corporate identity and domain name ownership of the website to prove that the applicant is a legitimate real entity. Users can see the name of the company applying for the SSL certificate in the certificate.

3.DV SSL Certificate-Domain name SSL Certificate

Form of expression: the address bar shows security lock + HTTPS, which is suitable for the official websites of small and medium-sized enterprises, small and medium-sized business websites, e-mail office servers, personal websites, etc., domain name verification and rapid issuance of certificates can be completed in about 10 minutes, without the need to submit paper documents, only to verify the domain name management rights, no need to manually verify the information of the applicant, fast issuance and low price.

This is how the SSL certificate shared by the editor has turned HTTP into HTTPS. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
