Email obfuscator plugin for Craft CMS 3.x

A simple plugin that adds a twig tag to obfuscate email addresses (by ROT13) in text fields.

Plugin Logo


This plugin is made for Craft CMS 3.0.0-beta.23 or later. It requires the Email-Obfuscator by Propaganistas since this plugin is merely a wrapper for his Twig Extension.


To install the plugin, follow these instructions.

  1. Open your terminal and go to your Craft project:

     cd /path/to/project
  2. Then tell Composer to load the plugin:

     composer require luke-nehemedia/craft-emailobfuscator
  3. In the Control Panel, go to Settings → Plugins and click the “Install” button for Craft Emailobfuscator.

You can also update your craft's composer.json file and run composer update.

Using the Plugin

This plugin adds the Twig Extension made by Propaganistas to Craft. It masks all email addresses by ROT13 ciphering or CSS reverse text direction. A simple javascript file decodes the masked emails on the frontend.

To use it, just use the obfuscateEmail Twig filter on any text field or string:

{{ "Sample Text"|obfuscateEmail }}
{{ textfield|obfuscateEmail }}

Configuring the Plugin


By default the plugin inserts the necessary JavaScript to your front end html. There is a setting to turn this off if you want to include the JS code manually. The relevant JS code is available at https://github.com/Propaganistas/Email-Obfuscator/tree/master/assets
