Signing Public Certificates using OpenSSL

Creating a Private Key and Certificate Signing Request (CSR)

Use the following OpenSSL command to generate a Private Key and a Certificate Signing Request for signing a public certificate against a public Certificate Authority

openssl req -newkey rsa:2048 -keyout login-hpnlab-net.key -out login-hpnlab-net.csr

 

Let's break down what this command is doing.

  * The green text options tell OpenSSL that we're requesting something

  * The yellow text options tell OpenSSL to create a private key

  * The red text options tell OpenSSL to create a Certificate Signing Request
