Generate the keys for the Certificate Authority (the key that will do the signing)

openssl genrsa -aes256 -out ca.key 4096
openssl req -new -x509 -days 3650 -key ca.key -out ca.crt

Generate the private key for your server

openssl genrsa -aes256 -out server.key 4096

Create a CSR (certificate signing request) to get signed by the CA

openssl req -new -key server.key -out server.csr

Sign your csr with the key you made in the first step

openssl x509 -req -days 3650 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

Optionally remove the password from your key (if you do this protect your key!!!)

openssl rsa -in server.key -out server.key.nopass

Add these lines to your Apache config

SSLEngine on SSLCertificateFile /www/ssl.crt/server.crt SSLCertificateKeyFile /www/ssl.key/server.key
