SSL is the abbreviation of Secure Socket Layer. SSL certificates have two main functions, namely identity authentication and data encryption. SSL certificates can authenticate the identity of a company or website. When users visit a website, they can click on the website security certificate and trust seal to learn about the specific information of the website and identify the authenticity of the website. In addition, SSL certificates can also enable HTTPS encryption to protect the personal information entered by users on your website, ensure that privacy-sensitive information is not illegally tampered with, and prevent the leakage of transmitted information.
CA is the abbreviation of Certificate Authority. CA is a third-party organization responsible for managing and issuing digital certificates. Its role is to check the legitimacy of the certificate holder's identity and issue certificates to prevent the certificates from being forged or tampered with. It can be understood that CA is similar to the public security bureau that issues ID cards to citizens. Therefore, not all companies can be called CA.

The purpose of users applying for SSL certificates is to implement HTTPS encryption on the Internet, protect website information security, and prevent website information from being hijacked or tampered with; corporate users need identity authentication to prevent corporate information from being used by people with ulterior motives, and at the same time, to allow visitors to browse, use, and trade on their websites with confidence. To gain the trust of browsers in the Internet industry, not just any HTTPS certificate can be achieved. Therefore, this requires a publicly trusted CA organization to verify the domain name ownership of the applicant. If you apply for an OV/EV SSL certificate, you must also cooperate to complete the corporate verification to confirm that the applicant is real and legitimate before issuing an SSL certificate.

This is because the email or phone number provided by the applicant cannot prove that it belongs to the applicant's unit personnel. It is possible that criminals are impersonating other units to apply for certificates for phishing websites. Therefore, domain name verification CA institutions can only recognize the administrator's email or Whois registration email; enterprise verification is completed through the phone or email queried by a third-party authoritative platform (generally corporate annual reports, 114 and other platforms).
