Short version of my question:
How do I use OpenSSL to create a non-self-signed certificate? This is assuming I already have a self-signed certificate and private key setup.
Long version of my question:
To create my self-signed certificate, I did the following:
openssl genrsa -out ca.key 1024
openssl req -new -x509 -days 1001 -key ca.key -out ca.cer
Now that I have ca.cer, the self-signed cert, how do I sign other certificates (ie, non-self-signed)?
