Creating an SSL Certificate

There are these steps that you need to follow:

  • Create a private key
  • Create CSR (Certificate Signing Request)
  • Submit the CSR to a Certificate Authority
  • Upload the Signed Certificate

Create a private key

openssl genrsa 2048 > private-key.pem

Create CSR (Certificate Signing Request)

openssl req -new -key private-key.pem -out csr.pem

The output will look similar to the following example:

into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank.
For some fields there will be a default value.
If you enter '.', the field will be left blank.
