How do I store keys for API's in Rails?

Question

I have several api's that I am integrating with and need to call in various parts of my application.

What is the way to store the keys, the user/password, or token information, say, a configuration file and then how do I call them for use in other parts of the application?

Thanks.

Just to keep this question up-to-date, there is a new way to do this in Rails 4.1:

From the Rails guides:

Rails 4.1 generates a new secrets.yml file in the config folder. By default, this file contains the application's secret_key_base, but it could also be used to store other secrets such as access keys for external APIs.
