Available with Rails 3 + 4 or above provides backward compatibility. This is a fork of the popular Rubygem ``simple_captcha`` which got abandoned.
* Zero FileSystem usage (secret code moved to db-store and image storageremoved).
* Provides various image styles. * Provides three level of complexity of images. * Works absolutely fine in distributed environment(session and db basedimplementation works fine in distributed environment).
* Implementation is as easy as just writing a single line in your view.```<%= show_simple_captcha %>``` within the 'form' tags.
* Flexible DOM and CSS handling(There is a separate view partial forrendering SimpleCaptcha DOM elements).
* Automated removal of 1 hour old unmatched simple_captcha data.
