How do I generate a CSR key?

Question

Hi there, I’m still kind of a huge noob to this. So I’ve created by own SSL certificate but I’d like to use one that’s been verified by a third party. However, this third party is requesting that I enter a CSR key. How do I go about generating one so I can incorporate a different SSL certificate?Thanks in advance!

Thanks guys. Now, how do I copy the CSR file to my desktop? Highlighting the text isn’t working on the console. Thanks

Thanks to ryanpq for the helpful answer ; I’d like to elaborate on the answer a bit. To the totally uninitiated in Ubuntu, as I am: You need to log into your Ubuntu server. First, I was trying to generate a csr from terminal on my PC, using ryanpq’s: openssl req -new -newkey rsa:2048 -nodes -keyout yourdomain.key -out yourdomain.csr Indeed, doing it from my PC, I was prompted through the list of questions - country, name, etc - and I was told a csr was generated, but I couldn’t find it anywhere on my PC. So, log into your server with ssh or whatever you use, where the csr will be hosted on. I don’t believe the csr generated on your PC is any use. I used sudo -s to log in as a super user. on my server, giving me root access. I put in ryanpq’s command and answered the questions that followed - name, challenge password etc. At the end of it all, I don’t think I got a confirmation that the csr had been generated, which would have been nice. I typed : ls -a (which means show files in currently directory) I saw one named mycompany.csr (my company being the actual name of my business) and typed: cat mycompany.csr (which opens that file) The csr file opens, displaying the csr password - everything between ‘BEGIN CERTIFICATE REQUEST’ and ‘END CERTIFICATE REQUEST’

After completing the questions you mentioned to provide the relevant details for your certificate this command would create a file called “yourdomain.csr” is your current directory that would have the signing request your certificate authority would need.
