Organizational Unit Name (eg, section) :ApplicationĬommon Name (e.g. Organization Name (eg, company) :Ansole Pvt Ltd. State or Province Name (full name) :Telengana Here is a general example for the CSR information prompt, when we run the OpenSSL command to generate the CSR. If we purchase an SSL certificate from a certificate authority (CA), it is very important and required that these additional fields like “Organization” should reflect your organization for details.

The next item in a DN is to provide the additional information about our business or organization. The important field in the DN is the Common Name (CN) which should be the FQND (Fully Qualified Domain Name) of the server or the host where we intend to use the certificate with. While generating a CSR, the system will prompt for information regarding the certificate and this information is called as Distinguished Name (DN). Both these components are merged into the certificate whenever we are signing for the CSR. A CSR consists of mainly the public key of a key pair, and some additional information. If we want to obtain SSL certificate from a certificate authority (CA), we must generate a certificate signing request (CSR).

This article helps you as a quick reference to understand OpenSSL commands which are very useful in common, and for everyday scenarios especially for system administrators. OpenSSL is a CLI (Command Line Tool) which can be used to secure the server to generate public key infrastructure (PKI) and HTTPS.
