Certificate Format
You can copy and paste the certificate body to create a certificate or directly upload the certificate.
A certificate issued by the Root CA is unique, and no additional certificates are required. The configured site is considered trustable by access devices such as a browser.
The body of the server and CA certificates must meet the following requirements:
The body of SM signing and encryption certificates must meet the following requirements:
- The content starts with -----BEGIN CERTIFICATE----- and ends with -----END CERTIFICATE-----.
- Each row contains 64 characters except the last row.
- There are no empty rows.
The following is an example:

Private Key Format
When creating a server certificate or server SM certificate, you also need to upload the private key of the certificate. You can copy and paste the private key content or directly upload the private key in the required format.
The private keys of server SM certificates must meet the requirements as described below.
Private keys must be unencrypted and meet the following requirements:
- The value must be in PEM format.
- The content must start with -----BEGIN RSA PRIVATE KEY----- and end with -----END RSA PRIVATE KEY-----.
