Email Obfuscator for Octopress

I want to include my email on my blog but I don’t want to store it in plain text - for obvious reasons. Originally I was going to use a third party script to do this since I couldn’t find an Octopress plugin that did what I was looking for.

Instead I decided to write my first Octopress plugin.

The plugin allows the following tag in markdown for obfuscating emails:

1

{% email test@example.com %}

This will render a script block that does the following:

  • Encodes the @ and . characters
  • Encodes the mailto: prefix
  • Reverses the email and uses CSS to display it to the user

The output from the plugin looks something like:

1
2
3

<script type="text/javascript">
document.write('<a style="unicode-bidi:bidi-override; direction: rtl;"href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;test&#64;example&#46;com">moc&#46;elpmaxe&#64;tset</a>');
</script>

I’m currently using the plugin on this blog as of today. Hopefully this is of use to someone else too!
