Digital Certificate Authority (CA) is a trusted third-party entity that issues digital certificate authorities and manages public keys and certificates that encrypt end-user data. The responsibility of CA is to ensure that the company or user receives a valid authentication is the only certificate.

The working principle of Digital Certificate Authority

As part of the Public key Infrastructure (PKI), CA uses a source of eligibility information (QIS) to check the data provided by the applicant before issuing a digital certificate. CA also has a close working relationship with third-party partners, such as credit reporting agencies. Authenticate the business and identity of the applicant. CA is a key component of data security and e-commerce, ensuring the true identity of both parties to the transaction.

The customer base of CA includes server administrators and website owners. Deploy the SSL certificate issued by the CA institution to the server, the SSL certificate can build a smooth and secure link between the authenticated server and the client, and the client and the server can communicate securely.

Among them, the CA/ browser Forum (CA/B Forum for short) is a self-disciplined industry organization that provides extensive guidelines for CA trust.

How do I get SSL from a digital certificate authority (CA)?

Digital Certificate Authority (CA) provides many types of SSL certificates, such as DV SSL certificate, OV SSL certificate and EV SSL certificate. Before obtaining a certificate, the requesting user must confirm which certificate is required. After confirming the type of certificate, select the target CA institution and apply for the purchase certificate.

After you apply for a SSL certificate, the next step is to generate a certificate signing request (CSR). After completing the CSR generation process, the CA institution will provide the private key to the customer in the form of a password. Then store the CSR and private key in a secure location on the server or local drive.

After receiving the certificate request, the CA organization will validate the applicant. Apply for different SSL certificates, and their verification methods are also different. The documents provided prove that the identity and business registration of the applicant depend on the type of certificate of the applicant.

To apply for a DV SSL certificate, CA only needs to verify the ownership of the domain. Once the verification is passed, the certificate can be issued within minutes. On the other hand, the verification process of OV and EV SSL certificates is relatively complicated, which usually takes 3-5 working days. Because the third party of the CA institution needs to verify all business-related documents. If the documents provided by the customer meet the requirements of CA, a certificate will be issued.
