I've created a small gem called multa_arcana (latin for "Many Secrets") which allows one to store all Rails secrets in one file, which should not be checked into revision control, but other files then can be.  Source is on https://github.com/skandragon/multa_arcana

Usage:

  add to Gemfile:  gem 'multa_arcana'

Create a file to hold the secrets:  config/secrets.yml
While the filename can be changed, it is somewhat hard to do so without modifying a file that is loaded fairly early, like application.rb.  I just use the default.  Currently to change this, one must pass in a file to load on the first call to retrieve a secret.  API suggestions welcome.

Place in this file the various secrets your rails app needs to keep secret:

db_username: john
db_password: my-super-secret-db-password
secret_token: lkasjdlkqjlkas...la9u9203udkd
redis: redis://user:password-for-redis@host
devise_pepper: 239ru2ij3jf9u02dhis...92930d02hdhdlka3

Use it wherever you need to:

config/database.yml:

production:
  adapter: postgresql
  encoding: unicode
  database: thing_production
  pool: 5
  host: 127.0.0.1
  username: <% MultaArcana::secret_for(:db_username) %>
  password: <% MultaArcana::secret_for(:db_password) %>


config/initializers/secret_token.rb:

Thing::Application.config.secret_token = MultaArcana::secret_for(:secret_token)

Interesting, but what advantage does this have over...

Probably none, but "settingslogic" didn't appear in my search when I looked for ways to store secrets in a single file.  :)

Sure there is advantage to writing your own gem. You wrote it, and
shared it with the community. That's AWESOME! I considered doing
something similar, until I ran across SettingsLogic.

Yes, environment variables are certainly an option, but I really like
the consistent API, and baked-in support for different environments that
SettingLogic provides.

Because environment variables show up in process lists.

If it's an issue of security...if somebody is already looking at your processes, what's keeping them from cd'ing to your application's config directory and reading secrets.yml?
