The first step is to generate and submit a CSR (Certificate Signing Request) file.
Generally speaking, CSR files can be generated online (or on the server). When the applicant makes them, the system will generate two keys, the public key CSR and the key key. After selecting the SSL certificate application, submit the order and submit the generated CSR file to the CA issuing authority where the certificate is located.
The second step is the authentication of CA institutions.
There are two ways for CA to verify the submitted SSL certificate application:
The first is domain name authentication. The system will automatically send a verification email to the administrator's mailbox of the domain name (this mailbox is the mailbox of the domain name contact found through the WHOIS information). After the administrator receives the email, click "I confirm" to complete the email verification. All types of SSL certificates must be authenticated by the domain name.
The second is the authentication of enterprise-related information. For enterprises applying for SSL certificate is OV SSL certificate or EV SSL certificate, in addition to domain name authentication, it is necessary to manually verify the relevant materials and information of the enterprise to ensure the authenticity of the enterprise.
Step 3: CA issues certificates.
Because the SSL certificate application mode is different, the verification materials and methods are somewhat different, so the issuance time is also different.
If you apply for a DV SSL certificate, it will take about 10 minutes at the earliest. If you apply for OV SSL certificate or EV SSL certificate, it will usually be issued within 3-7 working days.
