I have a javascript function on my other website which was used to 'encrypt' my email address.
It is different from other email address encrypters, mainly because it was easy to use and edit and didn't require use of an external program to do the encrypting for you.
You had to enter it in reverse format as domain.com@username and call the javascript function in the body of the page.
I simply modified the javascript function to accept the email address as an argument and then converted it into a plugin for wordpress.
