How to install SSL certificate in Apache

Generate a secure key for the domain:

$ openssl genrsa -out domain.key 1024

Generate a self-signed certificate:

$ openssl req -new -x509 -days 365 -key domain.key -out domain.crt

Generate a signed request if you want to have a valid certificate:

$ openssl req -new -key domain.key -out domain.csr

Submit the request to SSL certificate provider. Get signed certificate and save it to domain.crt.

Next, set up Apache to utilize the certificate.
