SSL, or Secure Sockets Layer, is a technology that creates an encrypted connection between clients and the server. This is necessary if we want to ensure that the data transferred to our server is encrypted; this includes data such as credit card information.

Setting up SSL can be painful because it requires some command-line knowledge. We like to buy our SSL certificates from https://www.namecheap.com/ because they are cheap and they get the job done.

The cheapest SSL certificate that you can get is PositiveSSL; you can find the offering at this endpoint: https://www.namecheap.com/security/ssl-certificates/single-domain.aspx.

After buying the certificate, you will need to generate a Certificate Signing Request (CSR). Let's do this. You will be first redirected to your Purchase Summary. Click on Manage:

mkdir .csr
cd .csr...
