Today, what the editor shares with you is the concept and function of the SSL certificate, which many people do not quite understand. Today, in order to let you know more about the SSL certificate, the editor summarizes the following contents. Let's take a look at it. I'm sure you'll get something.

Before you understand the role of SSL certificates, let's briefly talk about the concept of SSL.

I. the concept of SSL

SSL is an acronym for secure socket layer, which is a technology that encrypts communication between users and websites. This encryption ensures that important data, such as usernames, passwords, and credit card information, is sent from the user to the site without the risk of being intercepted.

For ordinary people, you don't need to understand the concept of SSL, but you only need to know that websites that use SSL protocols are more secure than those that don't use SSL protocols.

What is the use of SSL certificate

A: the role of security

1) 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.

The role of image

Google announced in 2014 that it would consider https as a lightweight factor to encourage cyber security. Even beyond Google's advice, sites that switch to SSL often find that customers think their sites are more authentic. The site is also more protected from damage that may be caused by third parties. Recently, Google warned Chrome users that web browsers would start re-tagging websites that are still on http: "from October 2017, Chrome will display an 'unsafe' warning in two other cases: when users enter data on digital certificate pages, and enter data on all http pages accessed anonymously."

This message is now displayed in the URL bar of the Chrome browser:

Increase the weight of SEO search

It is important to note that from switching to HTTPS, Google, Baidu search engine has prompted its weight.

Third, the application field of SSL certificate

It is mostly used in web sites with high requirements for information security, such as finance, securities, e-commerce, schools, medical care, social security and so on. Authenticate the true identity of the server to prevent personal information from being stolen.

SSL certificate securely encrypts the website, which can effectively prevent hijacking, prevent your website from being maliciously implanted with advertisements, prevent tampering and monitoring from leaking users' passwords, and optimize the SEO ranking of search engines with SSL certificates.
