password.weak?('admin123')
=> true
> password.errors

[[:password, ["it is based on a dictionary word"]]]

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

$ guard #  require './lib/cracklib_reloaded'

CAUTION: Using password as a script argument may not be safe

$ ruby init.rb 'admin123'
Equivalent of ActiveModel::Errors#messages
{:password=>["it is based on a dictionary word"]}
[[:password, ["it is based on a dictionary word"]]]
