Cryptex | Email Address Obfuscation

Cryptex transforms plain-text E-Mail-Addresses into Images - automatically - No scrapers. No harvesters. No spambots. That's our goal!

The plugin is used to display email addresses - that are normally expressed in plain text - 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!

Plugin Features

  • Fully customizable appearance: you can configure font-family, font-size and font-color - everything looks like your theme style
  • Retina/HD/High-Dpi Images - best appearance on all devices (2x, 3x or 4x resolution enhancement)
  • Shortcode and/or Autodetection usage!
  • Build-In E-Mail-Address-Autodetection - all addresses on your page are protected automatically (if you want it - you can also just use shortcodes!)
  • Autodetection filters configurable for the_content, the_excerpt, comments, comments_excerpt, text-widget
  • Reversible Address-Autodetection Process - your content is modified as long as the plugin is activated
  • Postal-addresses, telephone-numbers, names and other sensitive information`s can be protected too
  • Protects E-Mail hyperlinks (mailto) by using javascript based key-shifting encryption/decryption with dynamic keys - but you can use images only
  • Suitable for high traffic sites - automated caching of dynamic generated images and CSS
  • Automatic font-search (standard system font-paths)
  • Supports the new modern UI style of WordPress 3.8
  • Native support for Enlighter Syntax Highlighter to display E-Mail Addresses within highlighted content (requires Enlighter v2.7)
  • Includes the Liberation(tm) Fonts package
  • TrueType as well as OpenType Fonts are supported


    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
