Enigma

The Enigma plugin uses an encryption mechanism to hide text and only decode it when loaded from a browser on the client's side (via JavaScript).

This makes the text invisible for spam and search bots, and visible only for a person's eyes.

Enigma is usable via shortcode. Usage instructions are included with the plugin's README.

Installation:

Unpack and upload it to the /wp-content/plugins/ directory.
Activate the plugin through the 'Plugins' menu in WordPress.
