Zxcvbn Ruby 开源项目教程 Csdn博客

This is a Ruby port of Dropbox's zxcvbn.js JavaScript library. zxcvbn-ruby is considered stable and is used in projects around Envato. After checking out the repository, run bundle install to install dependencies. Then, run rake spec to run the tests. 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. Add the following to your project's Gemfile : gem 'zxcvbn-ruby', require: 'zxcvbn' Example usage: $ irb >> require 'zxcvbn' => true >> pp Zxcvbn.test('@lfred2004', ['alfred']) #<Zxcvbn::Score:0x00007f7f590610c8 @calc_time=0.0055760000250302255, @crack_time=0.012, @crack_time_display="instant", @entropy=7.895, @feedback= #<Zxcvbn::Feedback:0x00007f7f59060150 @suggestions= ["Add another word or two.

If you you'd prefer to persist the dictionaries in memory (approx 20MB RSS) to perform lots of password tests in succession then you can use the Zxcvbn::Tester API: $ irb >> require 'zxcvbn' => true >> tester = Zxcvbn::Tester.new => #<Zxcvbn::Tester:0x3fe99d869aa4> >> pp tester.test('@lfred2004', ['alfred']) #<Zxcvbn::Score:0x00007f7f586fcf50 @calc_time=0.00631899997824803, @crack_time=0.012, @crack_time_display="instant", @entropy=7.895, @feedback= #<Zxcvbn::Feedback:0x00007f7f586fcac8 @suggestions= ["Add another word or two.

For this reason we advise you not to store the results of Zxcvbn::Tester#test .
