You need to insert them into the certificate during the signing process.ĭuring the CSR generation, you are prompted to provide identifying information which is known as a Distinguished Name (DN). The CSR includes the public key of a key pair and some additional information. Let’s start! Section 1: Understanding Certificate Signing Requests (CSRs)Ī certificate signing request is a prerequisite when obtaining an SSL certificate from a certificate authority (CA). Each section contains a command-line snippet to accomplish what the subtitle states. However, if you are already familiar with it, you can skip to any other section relevant to what you are trying to achieve. The first part explains all you need to know about Certificate Signing Requests (CSR). This tutorial is a cheat sheet style guide, including some but probably not all OpenSSL commands that you may use in everyday scenarios. Thus, it is paramount to serve your website traffic over the encrypted HTTPS protocol. Some browsers like Chrome and Firefox may mark your website as Not Secure if you do not have a proper SSL certificate. Moreover, Google, which is a top search engine, gives priority to websites with SSL certificates implemented. Obtaining SSL the right way is crucial to your website’s security. OpenSSL is important because it ensures proper SSL implementation. The OpenSSL command will help you perform various tasks including Certificate Signing Request (CSR), private keys generation, and SSL certification. OpenSSL was released in 1998 and is available for Windows, Linux, macOS, and BSD systems. OpenSSL is an open-source cryptography library that includes a variety of commands used in the TLS Protocol and Public Key Infrastructure.
