NOTE: this plugin is targeted to advanced users and professionals – it requires some configuration tasks and won’t work out-of-the-box!
The plugin is used to display Email addresses as an image – automatically.
This will stop harvesters and crawlers from gathering sensitive data from your website.
It works with emails, telephone numbers, postal addresses or any other text-content.
Just wrap your E-Mail-Address into a shortcode like [email]youraddress@example.com[/email] – that’s it.
Or use the Autodetect filter to transform every E-Mail-Address on your page automatically into an image!

Text-Transformations
The @-sign as well as dot’s within the e-mail-addresses can be automatically replaced by different placeholders, e.g. mail(at)example{dot}org, to match your website’s corporate design.
Security Modes
Cryptex provides various obfuscation modes for E-Mail-Addresses:
- Plain Text – only text-transformations are applied – no use of images
- Single Image – the e-mail-address is expressed as a single image
- Multipart Image – the e-mail-address is splitted into two images, seperated by the @-sign in plain text
- Advanced Multipart Image – the craziest one: each part (divided by dot’s and @ sign) is displayed as a seperate image, the dividers as plain text
