## Popis

This plugin will integrate jQuery plugin Hashcash.IO (https://github.com/hashcash/
jquery.hashcash.io) to be used in combination with https://hashcash.io/ service.

Active development happens in GitHub repository – https://github.com/hashcash/wordpress-
hashcash

Please report all issues at https://github.com/hashcash/wordpress-hashcash/issues

Because of the way plugins work, problem might arrise from specific combination 
of WP version, plugins, themes.
 Therefore for the best result everytime you submit
a bug report or just seeking an advice please include following:

 * Version of WordPress you are using
 * Brand and version of Browser you are using to test it
 * List of third-party plugins and their versions activated on your website
 * What theme and version you are using

### Protect Against Web Spam

Typically various „Internet SEO Companies“ try to leverage poor forum software protection
against mass submission and create many worthless posts with links to a website 
they are promoting.

Some forum and blog software implement various CAPTCHA solutions but these have 
two negative aspects:

 * They annoy your visitors.
 * They provide a fake sense of security.
 * Today it is possible to buy access to API which solves any kind of CAPTCHA for
   just $0.70 per 1000 CAPTCHA images solved by a real human being. And do you really
   think your customer will be happy to try to solve one of these ridiculous CAPTCHAs?

### Secure Against Brute Force Attacks

Many modern applications are susceptible to brute force attacks. Take a typical 
login form, for example. Hackers can compromise account security by trying every
possible password combination. They can also leverage a large network of proxy servers
to paralelize this attack. Forcing their browser to work hard makes it too expensive
and slow for hackers to perform a brute force attack.

### Based On Open Technologies

We leverage the following features:

 * Asm.js
 * HTML5
 * Web Workers

Browsers supported:

 * Google Chrome 28+
 * Mozilla Firefox 22+
 * Internet Explorer 10+
 * Opera 18+

### Fully translatable

All strings are available for translation

### Fully accessible

We follow both common sense and accessibility guidelines to make this
 widget accessible
to people with limited abilities. We make it focusable and actionable via Tab-Enter
keys, as well as we have WAI-ARIA live region which updates blind user via screen
reader about progress.
