The bcrypt Ruby gem provides a simple wrapper for safely handling passwords.

Bcrypt-ruby gem is a sophisticated and secure hash algorithm designed by The OpenBSD project for hashing passwords. The bcrypt Ruby gem provides a simple wrapper for safely handling passwords.

If you store user passwords in the clear, then an attacker who steals a copy of your database has a giant list of emails and passwords. Some of your users will only have one password -- for their email account, for their banking account, for your application. A simple hack could escalate into massive identity theft.

It's your responsibility as a web developer to make your web application secure -- blaming your users for not being security experts is not a professional response to risk.
