<1> Provides information about the node that this certificate is intended for. In the past, this field specified the node's identity using a DNS name, but that behavior has been deprecated.

.Extended Key Usage
==========================
The Extended Key Usage attribute in a certificate is used to indicate the purpose of the key. By default `keytool` does not set this attribute in the certificate. If you are generating your certificates with another tool, please ensure the certificates support both `serverAuth` and `clientAuth` if the Extended Key Usage attribute is set.
