Creating self signed certificate using OpenSSL

A self-signed certificate is a certificate that is issued by the person or entity that will use it, rather than by a trusted certificate authority (CA). These certificates are commonly used for testing or for small websites that don’t handle sensitive information. In this post, we’ll show you how to create a self-signed certificate using OpenSSL. We’ll walk you through the process of generating a private key, creating a certificate signing request (CSR), and generating the self-signed certificate.
