Using hostname only instead of FQDN in certificate

Question

Can a localhost's name be used on a self signed certificate and used internally for the applications running on the same localhost?

I am just trying to test my applications with certificates.

Forgive my ignorance I am new to deploying certs.

Depends on whether those applications are willing to accept a self-signed certificate. — ceejayoz, Jun 15 '21 at 12:02
Why you ever need to use a localhost certificate? Certificate on localhost provides zero benefits because all traffic is passed through a software loopback adapter. — Crypt32, Jun 15 '21 at 13:49

You can use any hostname and IP-address in self signed certificates.

Note that using encryption to communicate between services running on the same host provides no security benefit at all and only creates additional overhead...
