This article will explain in detail why you need SSL Certificates. Xiaobian thinks it is quite practical, so share it with you for reference. I hope you can gain something after reading this article.

What are SSL Certificates

Many people may not know what SSL Certificates are. In fact, the concept of SSL Certificates is very simple. SSL Certificates are small data files that can digitally bind encryption keys to user details. After the Web server installs SSL Certificates, the HTTPS protocol can be enabled, allowing communication between client browsers and the Web server to establish a secure link. HTTPS encryption protocol can protect the security of users 'private information (bank card number, login account number, password), HTTPS protocol and gradually become known as the standard for protecting social media website browsing.

What are SSL Certificates

1. encryption key

2. Domain name, server name, or host name

3. Applicant's business information (e.g. business name)

Users who install SSL Certificates on a website Web server can establish a secure link (HTTPS) between the browser and the server. Once a secure link is established, all data transfers between the Web server and the browser are secure.

For HTTPS enabled websites, the "Security Lock" icon will appear in the navigation bar of the browser. If the EV certificate is purchased, the IE browser will also appear in the green address bar and display the name of the enterprise.

What does SSL Certificates do?

SSL Certificates encrypt data using asymmetric encryption algorithms.

This is a special encryption algorithm that uses two keys to encrypt data. These two keys are randomly generated long strings of numbers, one called a private key and one called a public key. The public key is published on the web by the web server, so that anyone can get the public key, but the private key is stored on the server. When the user needs to send information to the server, the browser encrypts the data using the public key, and this encryption can only be broken using the private key. After the browser encrypts the data, it sends the encrypted data to the server. Since only the server keeps the private key, only the server can decrypt the encrypted data. In this way, it can ensure that the browser will not leak user data in the process of transmitting data, so it can ensure the security of information transmission.

Why do I need SSL Certificates

In addition to protecting sensitive user information, SSL Certificates can:

1. Secure data transmission between servers and servers;

2. Improve search engine rankings;

3. Enhance customer trust;

4. improve transmission efficiency;

Where can I buy SSL Certificates (SSL Certificates request link https://www.it163.com/ssl.html)

First you must purchase a certificate from a trusted SSL Certificates authority. Because CA root certificates from these trusted certification authorities are recognized by browsers and operating systems.

The root certificate of the SSL Certificates you buy must be on the computer's certificate trusted list. If the certificate is not trusted, the browser will display a security warning to the user. If you visit your website and the page displays a security warning message, it will greatly affect your website image and users will lose confidence in your website.

About why you need SSL Certificates to share here, I hope the above content can be of some help to you, you can learn more knowledge. If you think the article is good, you can share it so that more people can see it.
