What is the reason for a website to deploy a SSL certificate? Many people do not understand, today the editor in order to let you know more about the SSL certificate, so give you a summary of the following content, let's look down together. I'm sure you'll get something.

Does your website need to deploy SSL certificates? To answer this question, let's first introduce what a SSL certificate is.

What is the SSL digital certificate

SSL digital certificate is a kind of digital certificate (abbreviated as certificate), which is called SSL certificate for short. A digital certificate is a certificate issued by a CA institution for the digital identity of a terminal entity. It represents the identity of the terminal entity, and the SSL certificate represents the server on which the SSL certificate is deployed (usually corresponding to the server domain name or IP address).

Simply put, SSL certificate = SSL+ certificate

An SSL certificate is a small data file that digitally binds encryption keys to organizational details. When installed on a Web server, it activates the padlock and HTTPS protocol and allows a secure connection from the Web server to the browser. SSL, which is typically used to secure credit card transactions, data transfer and login, has recently become the standard for ensuring the security of browsing social media sites.

The organization needs to deploy the SSL certificate to its Web server to start a secure session with the browser. Once a secure connection is established, all Web communication between the Web server and the Web browser will be secure.

After the certificate is successfully installed on the server, the application protocol (also known as HTTP) changes to HTTPS, where "s" stands for "secure". Depending on the type of certificate you purchased and the browser in which you surf the web, when you visit the website where the SSL certificate is deployed, the browser will display a padlock or green bar in the browser.

2. How does the SSL certificate work?

SSL certificates use a method called public key encryption.

This special cryptography takes advantage of the power of two keys, which are randomly generated long strings of numbers. One is called the private key and the other is called the public key. A public key is known to your server and is available in the public domain. It can be used to encrypt any message. If Alice wants to send a message to Bob, she will lock it with Bob's public key, but the only way to decrypt it is to unlock it with Bob's private key. Bob is the only one who has his own private key, so Bob is the only one who can use this to unlock Alice's message. If hackers intercept the Bob message before it is unlocked, they will only get a password that they cannot crack, even with the power of the computer.

If we look at this from the perspective of a website, then the communication takes place between a website and a server. Your website and server are Alice and Bob.

Why do I need to deploy SSL certificates on my website?

1) SSL certificate protects your sensitive information, such as credit card information, user name, password, etc.

2) ensure the security of data between servers

3) improve your search ranking

4) build / enhance customer trust

5) improve customer conversion rate

The above is a brief introduction to the reasons for the deployment of SSL certificates on the website. Of course, the differences in the detailed use of the above must be understood only after you have used them. If you want to know more, welcome to follow the industry information channel!
