Download of EmailCloaker 1.2 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The actual developer of this free Mac application is A!K Research Labs. The software lies within Developer Tools, more precisely Webmaster Tools.
From the developer:
Email Cloaker for Web - Simple utility generates code that cloaks e-mail addresses in HTML and prevents them from being harvested by spam spiders. At present some programs collecting email addresses can already decrypt addresses encrypted with almost any method and add them to their database. Neither javascript cloak, nor html cloak can help.
