What kind of organization is the CA institution?

SSL certificate plays an irreplaceable role in Internet transmission, not only because it protects the private data left by customers when browsing web sites, but also because it can show the credibility and reliability of a web address. Therefore, the SSL certificate can be said to be the standard of modern network information transmission. For many people who are new to the Internet, this term may be strange, and they don't know where the SSL certificate comes from. In fact, SSL certificates are digital certificates issued by CA institutions. About CA institutions, the editor will give you a related introduction.

CA institution is the department that issues ssl certificates. There are three types of ssl certificates: EV, OV and DV certificates:

CA institution is the digital certificate authorization center, which, as a trusted third party in e-commerce transactions, bears the responsibility of verifying the legitimacy of the public key in the public key system. The CA center issues a digital certificate for each user who uses a public key. SSL certificate is one of the digital certificates issued by CA institutions. The function of the SSL certificate is to prove that the URL of the deployed SSL certificate has a legitimate public key. The digital signature of CA makes it impossible for attackers to forge and tamper with certificates. It is responsible for generating, distributing and managing digital certificates needed by all individuals involved in online transactions, so it is the core link of secure electronic transactions.

The CA center is a network institution that manages and issues security credentials and encrypted information security keys. The registry (RA) verifies the digital certificate provided by the applicant, and the certificate is issued after CA verification. For example, to apply for a SSL certificate, CA institutions can issue a SSL certificate to you after verification, which includes the applicant's personal information, public key and validity period of authentication, as the basis for online identity proof.

Thus it can be seen that the construction of CA center is an indispensable part of the development of the information age. In order to ensure the security and reliability of the information left by users when browsing the web site, CA institutions need to verify the authenticity of the user's identity and then issue the corresponding SSL certificate to these web sites that have passed the security test.
