I need to get SSL certificates reissued for about 30 of my clients. I was hoping for an easy way to get the contents of their currents CSRs, pipe them in to
openssl req -new ... and generate a whole new set of CSRs and new keys. I saw on the openssl man page that you can do
openssl x509 -x509toreq -in cert.pem -out req.pem -signkey key.pem but this expects key.pem to already be created.
Can anyone help with a way to do this other than viewing the contents of each individual cert and copy-n-pasting in to the new request?
