What is the purpose of a self-signed certificate?

By having a self-signed certificate you are effectively on your own, without the backing of a trusted certificate authority and application of the latest cryptographic methods necessary to ensure proper authentication and encryption of data, devices, and applications.

How do I create a self-signed certificate on Red Hat Enterprise Linux?

This procedure enables you to create a self-signed certificate using utilities which are available on Red Hat Enterprise Linux. You need the keytool utility, which is provided by any Java Development Kit implementation. OpenJDK on Red Hat Enterprise Linux installs this command to /usr/bin/keytool.

Run the following command to generate a certificate signing request using the public key from the keystore you created in step 1. You are prompted for the password in order to authenticate to the keystore. The keytool command then creates a new certificate signing request called certreq.csr in the current working directory.

How do I generate SSH Certificate Signing keys?

Generating SSH CA Certificate Signing Keys On the server designated to be the CA, generate two keys for use in signing certificates. These are the keys that all other hosts need to trust. Choose suitable names, for example ca_user_key and ca_host_key.
