What is the function of SSL certificate? I believe many inexperienced people are at a loss about it. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

What is a SSL service?

SSL (Secure Sockets Layer secure Sockets layer) and its successor Transport layer Security (Transport Layer Security,TLS) are security protocols that provide security and data integrity for network communications. TLS and SSL encrypt the network connection at the transport layer.

The main services provided by the SSL protocol are:

1. Authenticate users and servers to ensure that data is sent to the correct clients and servers

2. Encrypt data to prevent data from being stolen

3. Maintain the integrity of the data and ensure that the data is not changed in the process of transmission.

It is recommended that you use the SSL protocol when setting up your mailbox, which will ensure the more secure use of your mailbox.

The main role of SSL service certificate

Implement encrypted transmission

When users visit the website through the http protocol, there is a clear text transmission between the browser and the server, which means that the password, account number, transaction records and other confidential information filled in by the user are all plaintext, which may be leaked, stolen, tampered with and used by hackers at any time.

After installing the SSL certificate, using Https protocol to encrypt and visit the website, you can activate the "SSL encryption channel" (SSL protocol) between the client browser and the website server, achieve high-intensity two-way encrypted transmission, and prevent the transmission data from being leaked or tampered with.

Authenticate the real identity of the server

Phishing fraudulent websites are rampant, how can users identify whether the website is a phishing website or a secure website? After the website deploys the globally trusted SSL certificate, the browser has a built-in security mechanism to check the status of the certificate in real time, and display the authentication information of the website to users through the browser, so that users can easily identify the true identity of the website and prevent phishing websites from counterfeiting.

After the globally trusted Walton SSL certificate is deployed on the website, the browser can visually display the authentication logo and website authentication information:

1. The access address has been changed from "Http" plaintext access to "Https" encrypted access to ensure that the transmitted data is not compromised or tampered with.

two。 The browser displays the eye-catching security lock. Click the security lock to view the details of the website authentication.

Using the highest level EV SSL certificate, the browser displays the green address bar, and the status bar visually displays the name of the organization and the authority.
