Email Protector is an easy to use ASP.Net web control that hides email addresses from harvesters.
The email address is encrypted using the XTea algorithm. (http://en.wikipedia.org/wiki/XTEA)
Both plain text and fully functional mailto links are supported.
The web control can be populated declaratively in a web page or programmatically from code.
This allows for static as well dynamically loaded email addresses to be encrypted.
