Voynex Email Guard is a JavaScript script designed to protect email addresses on a Web site from email harvesting software while making this protection transparent (invisible) for the Web site visitor. Users can still click, copy, and paste email addresses without knowing that the email address on the Web site is encrypted. Voynex Email Guard transforms email addresses on a Web page into a format that is unreadable for email harvester robots, but makes these addresses readable again for Web site visitors.
