droideka

fight back against email scrapers

What it does

• finds all <a href="mailto:... email addresses in your html
• encrypts them
• appends some JS to your html that decrypts them 1/2 second after the page loads

How to use it

var droideka = require('droideka');

html = droideka(html[, seed])

Your HTML

<p>
  Here is my email:
  <a href="mailto:some@email">[email protected]</a>
</p>
<p>
  Here is some more html stuff
</p>

In node run it through droideka

html = droideka(html);

Here is the output

<p>
  Here is my email:
  <span id="cihzenf7j0000i4dxll7gftvj"><noscript>You must enable JavaScript to see the email.</noscript></span>
</p>
<p>
  Here is some more html stuff
</p>
<script type="application/javascript">setTimeout(function(){var d=function(b){var c=b.substring(0,87);b=b.substring(c.length);var e,f,g,h='',d;for(e=0;e<b.length;e++)f=b.charAt(e),g=c.indexOf(f),d=(g-b.length+c.length)%c.length,d=0>d?c.length+d:d,h+=0<=g?c[d]:f;return h};(function(){var a=document.getElementById("cihzenf7j0000i4dxll7gftvj");if(!a)return;a.innerHTML=d("eY\"1]U.ZbrBtmCh[-:VpK!6WuXx8dlwM2GJ,kfT#(RHD&5L}I^o7~F*4S0{qzO%n3>gsQPvA'@cyjN<9=)a+iE$Gf S7H9,&*f#AFUq6U*HdH*f#A&K6U*HdH*f#AG/fK");}());}, 500);</script>

Take that spammers!

seed can be any string, i.e. your package.json's version string.

encoded = droideka.encode(text[, seed])

Lightly encrypt some text. (not cryptographically secure)

droideka.js_code_decode

A string of JS code that creates a local function d that can be used for decoding.

haml += '<script>';
html += droideka.js_code_decode;//insert the decoding function
html += 'var email = d(' + JSON.stringify(encoded) + ');';//call it
html += '</script>';
