Generate a CSR with openssl

Generate a CSR (Certificate Signing Request) on your server when you want to get a certificate from a certified provider is often a mandatory step, very easy to execute.

Here are the different steps to execute:

  1. Create a specific directory where you will put all your files
  2. Generate a private key of 2048 bits
  3. Now generate a CSR with openssl and with the private key you just generated

  4. You now have your CSR and your private key

It’s up to you to get your signed certificate from an official provider using those files.
