A website SSL security certificate is specifically a digital file that is audited and issued by a trusted digital certificate authority (CA agency). It contains information issued by the CA indicating that the website has been securely protected using an encrypted connection. .
Website SSL security certificate is also called SSL certificate, https certificate and server certificate, its main function is to protect the basic security of the website. And every website with this certificate installed will display a green security lock and https prefix.
Why is a website SSL security certificate important?
Because with a website security certificate, users can be sure: they are connected to the correct official server of the website they want to visit, and no one can intercept the data they send to the website and use it for other purposes.
Website SSL security certificate can encrypt and protect sensitive information
The main reason for using an SSL certificate is to encrypt sensitive information sent over the Internet so that only the intended recipient can access it. And this is very important because without encryption using an SSL certificate, the data is transmitted in clear text and any third party can view the user's credit card number, username and password, and other sensitive information, and when using an SSL certificate, everything except the expected The information cannot be read by any third party except the recipient.
Website SSL security certificate provides trust
For websites that do not have an SSL certificate installed, major browsers will issue an "insecure" warning in the address bar. For websites that have an SSL certificate installed, there will be no such warning. Instead, a green padlock icon and the beginning of https will appear. This indicates to users that the information they enter on the site is transmitted encrypted and cannot be intercepted by third parties.
Website SSL security certificates can be used for authentication to ensure that the organization is really there.
Commercial SSL certificates have a higher standard of verification than their free SSL CA counterparts when it comes to verifying an organization's identity. Of course, they do sell commercial DV certificates, but commercial CAs also offer Organization Validation OV and Extended Validation EV SSL certificates. Both certificates provide a form of business verification - OV is an intermediate level of verification, while EV, as its name describes, requires the most extensive verification.
For example, with an EV SSL certificate, it typically takes a few days for the CA to investigate your organization, review records, and confirm that your organization is legitimate and not just behind the scenes setting up a phishing site. This might sound like a huge pain for you as a website owner, but it's not. But it does mean that you have to be able to use legitimate documentation and channels to prove that your website is genuine and that you are a real established organization.
