MySecrets
I had some trouble integrating cucumber, pickle, machinist, and authlogic. A user has 0 to many secrets and secrets are protected by authlogic. So cucumber features that needed to add secrets and validate them were a little tricky.
This scenario creates a user, login in, creates a secret, shows the secret, and finally validates the secret.

| Scenario: Show Secret | |
| Given a user exists with username: "myuser", password: "secret", password_confirmation: "secret" | |
| And a secret exists with user: the user | |
| And the user is logged in with myuser/secret | |
| When I go to the show page for that secret | |
| Then I should see the secret |
The show pages are handled with a polymorphic_path.

pwfoo - Ruby Gem
pwfoo is a gemcutter.org hosted gem that I developed to generate random passwords, score the strength of passwords, and generate random seeds.
Generate password
Determine password strength
The SrandSeedGenerator is interesting because it uses the current time and currently running processes to generate random seeds.
pwfoo can be installed from gemcutter.org.
