SSL/HTTPS on Devise + Rails3

I have seen gems like ssl_requirement, but its too complicated for securing just two pages of user login and sign up.

Referred few blogs and found few useful links for the same:

1> For
# Creating your private key
# Creating your certificate signing request
# Getting your certificate
# Configuring your web server
Refer: http://www.buildingwebapps.com/articles/79189-using-ssl-in-rails-applications
2> For Setting up Rails app with Devise, I have referred this :
