Tutor Section: How to Encode Email addresses
Return to tutor homeThis is a Javascript Object used to encode email addresses in web pages in order to somewhat protect the user from e-mail harvesters. Utilizes Javascripts ability to modify the HTML document once it has been delivered to the client.
This works by encrypting an email address using simple XOR byte operations, then using Javascript to unencode it on the fly once it reaches the client (browser). This will fail if the harvester is sophisticated enough to execute the javascript and parse the results. However, many sources say this is a fairly safe way to go about it. Many other email protectors simply encode the email addresses into their character numbers, which is definently quite weaker than this method of simple encryption.
