software to encode/fuscate a web form?

[moroose]

Hi!
am looking for a program to encrypt/fuscate a web form so as to render it unreadable by spam bot.

I'd value your opinion
-Is such a software reliable and does it worth it to buy it?
-is there any php code that make such encryption(dont know if the mycrpt function can apply on a whole form)

thanks for your insights

I think your on the wrong track for spam prevention - besides you can't encrypt the actual form for clients using PHP - you'd have to use javascript to achieve something like that.

I would consider third spam prevention like akismet, or alternatively use some kind of checksum or hidden fields in the form to prevent automated use. If all else fails, and depending on the form, you could implement some kind of captcha.
