Produces PNG files (image files similar to GIFs, but
smaller) that contain your email address. When you post them
on your website, it is harder for spammer to harvest them.
You can include the generated image files in the HTML on
your website with: code like this:
<a href="../images/mailto/roedy.png">email me</a>
or
<img src="images/mailto/roedy.png" height="24" width="186" alt="my email address">
You can also mention your email address in public postings
like this:
   For my email address see http://mindprod.com/images/mailto/roedy.png
It can be read by humans, but it would be more difficult for
automation to harvest the name for spam lists.
You can also run it standalone as an application with
        java.exe -jar masker.jar
It also tells you what it should be sending.
You can also use it as a command line utility:
java.exe -jar mask.jar john@yahoo.com E:\temp\john.png
You can also use it in your own programs with
Mask.createMask( File pngfile, String email );
To install, Extract the zip download with WinZip, available
from http://www.winzip.com (or similar unzip utility) into
any directory you please, often C:\ -- ticking off the "user
folder names" option. To run as an application, type:
java.exe -jar C:\com\mindprod\masker\masker.jar
adjusting as necessary to account for where the jar file is.
The Applet must be signed to allow it to save the png image
on your local hard disk.

techniques to foil spam email harvesters.
Why the hockey mask logo?  It symbolises both hiding and
protecting.
