Cryptex | E-Mail Address Protection

Bởi Andi Dittrich
Tải về

Mô tả

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!

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

Installation

  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Go to Settings -> Cryptex and check all items into the sidebar.
  4. In case that there are no font available on your server you can use own/special fonts by uploading them into the /wp-content/plugins/cryptex/fonts/ directory
  5. Go to the appearance section and select the font-family, font-color and font-size like the styles in your theme
  6. That’s it! You’re done. You can now enter the following code into a post or page to protect email addresses: [email]youraddress@example.com[/email]. Or use the Autodetect feature

Hỏi đáp

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.php file 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 to 0644 or 0770

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

I miss some features / I found a bug

Flexible and good

25 Tháng tám, 2018
This is a fairly good and not too complicated plug-in which does a good job at scrambling e-mail addresses automatically on WP sites. Load the fonts you use and it can be fine-tuned to blend very well into the website. It may require a bit of work to fine-tune it to perfection, but it is well worth the efforts. This is not the plug-in for those who just wants something which works without any efforts. But the scrambling it does is well worth the effort.
