What is the wildcard SSL certificate? What's the use? Many people don't know much about it. Today, in order to let you know more about the wildcard SSL certificate, I summed up the following contents. Let's move on.

When Google browser began to identify traditional HTTP sites unsafely, more and more websites upgraded to HTTPS by installing SSL certificates. SSL digital certificates are classified into single domain name, multi-domain name and wildcard certificate, among which wildcard is very popular with users because of its expansibility. Of course, whether users need wildcard certificate or not and what kind of wildcard certificate they choose need to be decided according to the specific needs of the website.

What is the wildcard SSL certificate?

The wildcard SSL certificate is designed to protect the primary domain name and an unlimited number of subdomains, that is, users can protect any number of subdomains with a single wildcard SSL certificate. The wildcard feature not only helps users save money, but also helps users save valuable time about certificates. Therefore, if the user has more than one subdomain name platform, they can be protected by the wildcard SSL certificate.

Currently, domain name verification (DV) and organizational authentication (OV) SSL certificates support the wildcard feature, and a single wildcard SSL protects www and non-www domain names. After domain name verification (DV), the wildcard SSL certificate can be quickly released within a few minutes after domain name verification. After correct installation, the primary domain name and its unlimited number of subdomains can be protected. For the OV SSL certificate, you must submit the relevant business documents and domain name verification materials. The verification process takes 2-3 days. After all the materials are correct, the certificate can be issued.

A single wildcard SSL certificate has a 256-bit encryption strength and a 2048-bit certificate key length. Multiple server license policies that allow users to protect their websites on multiple servers. Under the unlimited reissue policy, users can reissue the certificate at will during the period of validity of the certificate. The security identity of the browser can enhance the confidence of client users.

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.
