Today, I would like to talk to you about the use of SS certificates, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something according to this article.
What is a SSL certificate?
A SSL certificate, also known as a server certificate, is a digital certificate that complies with the SSL protocol and is issued by a globally trusted certificate authority after verifying the identity of the server. Installing the SSL certificate on the website server can realize the dual functions of website authentication and data encryption and transmission.
Second, what is the use of SS certificates?
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.
two。 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.
3. 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.
The biggest advantage of SSL certificate is data security, avoiding the risk of information disclosure and reducing the probability of website being hijacked.
Moreover, after enabling the SSL certificate, the built-in security mechanism of the browser will check the status of the certificate in real time and display the security lock, green address bar and certificate information on the browser to show users the identity authentication information of the website and obtain the user trust.
In SEO included rankings, HTTPS not only will not affect the inclusion, but also can get a better SEO included rankings.
For example, Google will give higher rankings to sites with SSL certificates, which shows that HTTPS is very important to enterprises, regardless of whether they rely on the network business or not.
