Generating Certificates for OpenSearch Main Administrator

The system requires dedicated certificates for the administrator account. These certificates are essential for authenticating and authorizing a user with full access privileges to all cluster functions and data.

Files to be generated:

• admin-cert.pem — administrator certificate in PEM format

• admin-key.pem — administrator private key in PEM format

The certificate generation process for the main administrator follows the same procedure described in the Generating Certificates for Search Anywhere Framework Components, specifying the CN=admin parameter, but using a separate configuration file provided below. If necessary, you can set any other value of CN.
