What is CSR?
To obtain an SSL certificate via Certificate Signing Request (CSR), generate an CSR file and submit it to a certificate authority (CA). CSR includes a public key and a distinguished name. CSR is usually generated from a web server and a public and private key pair for encryption and decryption is created at the same time.
Relevant organization information is required to create a CSR. The web server creates a distinguished name based on the information provided to identify the certificate. The organization information includes the following items:
Country or region code
The code of the country/region where your organization is legally registered, in the two-letter format defined by the International Organization for Standardization (ISO).
Province, city or autonomous region
The province, city or autonomous region where your organization is located
The city/region where your organization is registered or located.
The legal registered name of your business
Departments within the Organization
This field is used to differentiate departments within an organization, such as "Engineering department" or "Human resources department".
The name entered in the CSR common name field must be the Fully Qualified Domain Name (FQDN) of the website to which you apply the certificate, for example "www.domainnamegoeshere".
However, Tencent Cloud generates CSR online without you having to generate and submit CSR files. To apply for a domain validation certificate, you simply need to submit a common name.
