Your non-production environments this step since it will only be used to refer to this machine in the /usr/share/easy-rsa on. Ensure you are logged into your CA server as your non-root user and run the following, substituting in your own server IP or DNS name in place of your_server_ip: Now that the file is on the remote system, the last step is to update any services with the new copy of the revocation list.

Using ubuntu certificate authority use a Ubuntu server 18.04 16.04 operating system a key inside it your servers, you do!

The modern approach is to become your own Certificate Authority (CA)! To create the root public and private key pair for your Certificate Authority, run the ./easy-rsa command again, this time with the build-ca option: In the output, you’ll see some lines about the OpenSSL version and you will be prompted to enter a passphrase for your key pair. We can also see that the Root CA is not trusted. We can see that certificate is issued by the same entity as the site-name itself. These certificates, although not created by trusted third party certificate authority (CA), it has the same level of encryption as trusted certificates. Following the practice example above, the Common Name of the certificate is sammy-server: This will ask you to confirm the revocation by entering yes: Note the highlighted value on the Revoking Certificate line.

Note: If you are using your CA with web servers and use Firefox as a browser you will need to import the public ca.crt certificate into Firefox directly. so rename it when necessary. In this section we will generate a master CA certificate/key, a server certificate/key, and certificates/keys for 3 separate clients. cd /usr/lib/ssl/misc/ sudo ./CA.sh -newca.
