About this plugin
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][email protected][/email] – that’s it.
Or use the Autodetect filter to transform every E-Mail-Address on your page automatically into an image!
Plugin Features
- Protects Email Adresses, Telephone Numbers or any other content
- 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
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
Questions
- Cryptex Shortcode doesn’t work in Text-Widgets
Generally, WordPress does not process any shortcodes used in text-widgets. You can add the following code to your template
functions.phpfile to enable shortcode processing:add_filter('widget_text', 'do_shortcode');- I get an error using the system font paths, which are shown by the settings page
This paths – depending on your hosting environment – can be different – if you don’t know the path, please ask your hosting provider or upload the fonts manually into the cryptex-plugin-directory
\wp-content\plugins\cryptex\fonts\and use Plugin Directory as font source.- I get a “file permission” error changing the font source to **Custom Directoy**
During security restrictions your system font paths could be unaccessable. In this case you have to upload TrueTypeFonts (.ttf) into the cryptex-plugin-directory
\wp-content\plugins\cryptex\fonts\and use Plugin Directory as font source.- I get an “file permission” php error in my blog
The directory
/wp-content/plugins/cryptex/cache/must be writeable – the images as well as the generated css file will be stored there. Try to set chmod to0644or0770- I need bold/italic font styles
Please use the italic/bold font of the font family you’ve selected. For example there is an verdana.ttf(normal) and verdanai.ttf(italic) file!
- Is it possible to use Cryptex directly in my wordpress template ? shortcode does not work yet
Of course! you can simply use
<?php Cryptex::crypt('yourtext'); ?>to display ‘yourtext’ as crypted version
