Are you hijacked by hackers because your website does not have an SSL certificate installed, resulting in user data loss?
Are you marked as an unsafe website by Chrome, Firefox and other browsers because your website does not have an SSL certificate installed?
Have you been hung on a phishing pop-up window because your website does not have an SSL certificate installed, resulting in a decrease in user trust and Baidu's ranking?
To solve the "untrusted", "unsafe", "ranking decline" and other problems of the above websites, you need to SSL certificate.
What is an SSL certificate?
The SSL certificate is actually an "ID card" in the online world. With this card, you have the right to prove that you are a real and reliable corporate or personal website in the online world, rather than a phishing website.
The enterprise activates the "encrypted channel" between the browser and the server - SSL protocol by installing a certificate, which is used to prevent the transmission data from being disclosed or tampered with.
When the website server has an SSL certificate, the URL column of the browser will start with https (Hyper Text Transfer Protocol Secure) to inform visitors that they are on the website protected by the SSL certificate.
Why must websites use SSL certificates?
1. Encrypt website data and protect website security
By installing and deploying SSL certificates, HTTPS can encrypt data with high strength to prevent users' private data from being attacked by hackers during information transmission. On the one hand, it can prevent user information disclosure, on the other hand, it can prevent websites from being impersonated by phishing websites, and avoid unnecessary loss of users and brand trust crisis.
2. Increase the trust of visitors
If it is not equipped, when visiting the site, users will encounter pop-up reminders such as "insecure connection" and "untrusted certificate". Most users will give up browsing or using the product after seeing such pop-up windows.
3. Get better search rankings
At the beginning of February 2018, Google's Chrome browser announced that it would "block" websites with HTTP protocol. The use of SSL certificates is an important indicator of SEO (search engine optimization). Therefore, if websites want to use natural search to improve traffic, it is recommended to use SSL certificates to increase website security.
How does an SSL certificate protect information security?
When users use the network to visit websites, there will be a large amount of data to exchange. At present, most of the network transmission protocols used are HTTP protocols, which are non encrypted protocols. The information is transmitted in clear text, lacking information security protection mechanisms, and low security.
In order to ensure stronger encryption and more secure transmission of data, the SSL certificate can be added to the HTTP protocol to improve the security of data, that is, the HTTPS protocol.
The SSL certificate is issued to the applicant by the certificate issuing authority (CA) after verification and review of the certificate applicant's information. The certificate issuing authority will generally verify and verify the domain name information of the applicant. If the application is for a higher level certificate, the certificate issuing authority will also verify the enterprise information of the applicant manually by telephone. The purpose of this is to ensure that the object of certificate issuance is true and effective, and to avoid malicious use of phishing websites, fake websites, etc, Cause losses to users or enterprises.
After the certificate issuance deployment and installation, the user uses the HTTPS protocol when visiting the website. The data exchange between the client and the server is encrypted, and the user's information security is guaranteed. Even if the information is obtained by the hacker, the content of the information is unknown to the hacker. Cracking the encrypted information also requires high costs, which is not worth the loss for criminals.
It is the above protective measures that make SSL certificate the preferred encryption scheme at present.
In November 2021, the State officially implemented an important law in the field of personal information protection - the Personal Information Protection Law of the People's Republic of China. The promulgation of the Personal Information Protection Law highlights the importance of current information security, and will also promote more enterprises and institutions, financial institutions, large e-commerce websites and other security measures to be upgraded.
The popularity of the HTPPS protocol across the network will only be a matter of time. With the tightening of external regulatory measures, it will be fully rolled out until it becomes a mainstream network security transmission protocol. The development of the SSL certificate industry will also usher in a golden opportunity period.
Why should mainstream browsers support https?
In order to provide users with a more secure network environment, many browsers have introduced https security rules to speed up the pace of promoting https encrypted websites. Websites that are not "https" will show "unsafe" in a prominent position.
Apple Safari browser: In mid November 2018, the 70 version of Safari technology preview was released, and the new version will add a more explicit "unsafe" warning in the smart search bar when loading http pages.
Google Chrome browser: In August 2018, Google Chrome completed a milestone update: it can directly mark unsafe http websites. As long as your website starts with http instead of https, it will be marked as "unsafe".
Firefox Firefox: As early as December 2017, Firefox Firefox marked websites that did not send passwords using the https protocol as "unsafe". The address bar will display a sign with a bar marked on the lock.
Chrome, Firefox, Safari and other mainstream browsers that warn against unsafe http pages cover about 60-70% of the user community. For websites that have not upgraded https, it is imperative to complete the https upgrade in time.
For visitors, unsafe warning messages are likely to make them immediately shut down your website, which increases the bounce rate of the website, thus reducing sales and conversion rate.
Which scenarios require SSL certificates?
In addition to mainstream browsers such as Chrome, QQ, 360, Firefox, Sogou, etc., https sites will be marked as "trusted sites" to display website and enterprise information, making it easier for users to have a sense of trust in websites. In addition, there are many scenarios that also need SSL certificates:
Applet must have: Applets have always been known as "APP killer". How can developers miss this wave of WeChat dividends on the business explosion that WeChat may bring with its huge social user base? However, WeChat also has many restrictions on small programs, such as file size, request server must be HTTPS, etc. To implement the server side HTTPS request, you need to configure the ssl certificate on the server side.
Apple App must have: On January 1, 2017, all apps in the Apple App Store must enable HTTPS connection network services to ensure user data security through transmission encryption.
It is necessary for twitter advertising: if you want to advertise on twitter, or add a page on twitter, there is no doubt that the page address of your website must be https access.
Mandatory public account: In 2017, the WeChat public platform announced that the public platform will no longer support HTTP calls, requiring developers to switch the existing services called through HTTP to HTTPS calls as soon as possible.
With the application scenarios related to Internet+and big data increasingly penetrating into people's lives, deploying SSL certificate encryption has become a future trend. SSL certificates will play an increasingly important role in protecting network security, online bidding, online signing, online shopping and payment, online office and other fields.
What is the use of SSL certificates for various industries?
Financial industry: The risk of a large number of private data exchanges under insecure transmission protocols is too high. SSL certificate encryption can solve this problem.
E-Commerce: The trust mark provided by the SSL certificate is convenient for users to correctly identify the real identity of the website, whether they can trust the website and conduct transactions, and encourage users to conduct transactions with confidence, thus improving sales business.
Government affairs platform: The information security of the government affairs platform is very important, enabling the SSL certificate of authoritative authentication can maximize the protection of information security and website credibility.
Large, medium and small enterprises: SSL certificates encrypt customer data securely, which can increase users' trust in the website. The website will rank higher in the search results, which is conducive to corporate image display and brand protection.
Is it enough for enterprises to choose the free SSL certificate?
The free certificate is a free DV SSL certificate, which can only protect a complete domain name and cannot support wildcards. This type of certificate can only verify domain name information, and is only applicable to simple HTTPS encryption requirements such as personal user experience or testing. And because the free SSL certificate audit project does not require manual audit, it not only gives hackers an opportunity to take advantage of it, but also may cause a crisis of trust in enterprises.
For the sake of the security of users and the website itself, we do not recommend administrators to choose free SSL certificates. This one-stop authentication is only the lowest authentication standard on the Internet and is not completely reliable.
How should I choose a commercial SSL certificate?
According to the certificate type, commercial certificates are mainly divided into: paid domain name DV SSL certificate, enterprise OV SSL certificate, and enhanced EV SSL certificate.
Domain name DV SSL certificate: It can encrypt website data to meet the needs of enterprises to bind multiple domain names and pan domain names. However, it can not prove the identity of the enterprise. It is only suitable for individuals and small and medium-sized enterprise websites.
Enterprise OV SSL certificate: It can encrypt website data to meet the needs of enterprises to bind multiple domain names and pan domain names. Provide "three pieces" to prove the authenticity of the website: green security lock, HTTPS transmission encryption, and enterprise identity query, which are applicable to all kinds of small and medium-sized enterprise websites.
Enhanced EV SSL Certificate: This is considered to be one of the most secure certificates available. The green address bar displays the company name+security lock+https, which is applicable to financial securities, banks, third-party payment, online shopping malls, etc., with emphasis on website security and brand credibility, involving transaction payment, customer privacy information and account password transmission. It is recommended to select the EV SSL certificate displayed in the green address bar, which is more trustworthy for users.
According to the type of domain name, commercial certificates can be divided into single domain name SSL certificate, multi domain name SSL certificate, and wildcard domain name SSL certificate.
Single domain SSL certificate: If you have a relatively simple and direct website based on content and only one domain name, a single domain SSL certificate is the best choice. Most personal websites fall into this category.
Multiple domain name SSL certificate: If you have a website with multiple domain names, you can choose a multiple domain name SSL certificate. You can easily protect multiple domain names by installing one certificate, which is very convenient for certificate management and renewal.
Wildcard SSL certificate: If your website has a subdomain name, you can choose a wildcard certificate. It can protect the universal domain name and all subdomains at the level you specified when you submitted the application. It is applicable to all subdomains at the same level under the same primary domain name. There is no limit to the number of subdomains.
