'Creates an HSM client certificate that an Amazon Redshift
cluster will use to connect to the client\'s HSM in order to
store and retrieve the keys used to encrypt the cluster
databases.
The command returns a public key, which you must store in the
HSM. In addition to creating the HSM certificate, you must
create an Amazon Redshift HSM configuration that provides a
cluster the information needed to store and use encryption
keys in the HSM. For more information, go to `Hardware
Security Modules`_ in the Amazon Redshift Management Guide.
:type hsm_client_certificate_identifier: string
:param hsm_client_certificate_identifier: The identifier to be assigned
to the new HSM client certificate that the cluster will use to
connect to the HSM to use the database encryption keys.'
