Generator for Cloaked Email Addresses

A Blue Link Webs Web Development Note

This tool generates a PNG image of a text email address, plus the HTML needed to insert it into a Web page and a JavaScript function to make it clickable. There are complete instructions on the result page. We believe this technique is resistant to most spammers' harvesting robots. Please read the "fine print" below.

 Type your e-mail address:
Select a link color: #0000CC: dark blue
#0000FF: "unvisited" blue
#990099: "visited" purple

Fine print: Your e-mail address will be sent to a shared server. Your address is evanescent on the server. It does find its way into the httpd log files as a result of dynamic generation of the graphic. We can't figure a way around this. Logs are rotated automatically, and the life of a particular log entry is about five weeks. We promise not to use that information for anything other than investigating trouble, and to exercise commercially reasonable efforts (a phrase with a legal meaning) to prevent others from doing so.

If you don't want to trust our server, you can do all this for yourself. Read on.

More information: There's a complete description of the motivation and process of cloaked e-mail addresses in: Read and enjoy.
