With the root certificate added to the list of trusted root certification authorities all the steps are done. When there is an HTTPS binding and you would try to visit https://acme-site.dev using Chrome in Windows, you would still see an warning page instead of the website itself. Opening https://acme-site.dev will no longer display any warnings, instead Chrome will display a nice “secure” status in the URL bar. So, to set up the certificate authority, I first generated a set of keys. It informs that accepting an CA certificate from an unknown origin is dangerous and to make sure the certificate is actually legit. genrsa vs genpkey: The OpenSSL genpkey utility has superseded the genrsa utility. Let’s break the command down: openssl is the command for running OpenSSL. Generate a private key file by using the following command: openssl genrsa -out qradar.key 2048. openssl genrsa -des3 -out key.pem 2048 . The big difference is the location where the root certificate should be imported into: Trusted Root Certification Authorities. Right now I’ve created a server.key and a server.crt file and these need to be combined into a single file. You may then enter commands directly, exiting with either a quit command or by issuing a termination signal with either Ctrl+C or Ctrl+D. In this example, I have used a key length of 2048 bits.
