The error is actually a `ActiveSupport::MessageEncryptor::InvalidMessage`, which means either the message you're trying to decrypt is corrupted (it isn't), or you have the wrong key. Since the `credentials.yml.enc` in the repo is the production credentials, the key for this is stored separately.

For development, just delete the file and when you run `credentials:edit` it'll be recreated for you with a valid key.
