Brother SP-1 - Import and Export the Certificate and Private Key

If you already have a certificate from an external trusted CA, you can store the certificate and private key on the
machine and manage them by importing and exporting. If you do not have a certificate from an external trusted CA,
create a Certificate Signing Request (CSR), send it to a CA for authentication, and install the returned certificate
on your machine.
