Though I would ask..... again!

Is there a CoffeeCup utility program or something, or even just a way I
can feed in a string of text and get valid encrypted HTML/PHP code out.
That I can then paste into my header that points to 'Email Me'....
I get a lot of spam, and my son Andrew has mentioned that he encrypts his 'mailto' stuff with a long string of meaningful.... Apparently.... Encrypted characters.
The 'Bots' cant read it as a valid email address, so he as a result, gets 'No Spam'.
Sooo... There is a way, just, I thought I would ask here, and try to be 'independant'....

If you know what I mean
