it cannot be read or exported later.

certificate will be a self-signed root CA. Otherwise, this mount

will act as an intermediate CA; a CSR will be returned, to be signed
|

by your chosen CA (which could be another mount of this backend).
|
|
Note that the CRL path will be set to this mount's CRL path; if you
|
|
need further customization it is recommended that you create a CSR
|
|
separately and get it signed. Either way, use the "config/ca/set"

endpoint to load the signed certificate into Vault.
