An E-mail form with captcha — I challenge you all!

During 20 miutes of boredom, I added a more or less complicated captcha to my contact form. It’s based on a 256 bit encryption, session handling and Gd image generation.
Spammers made me sick, they send any carp, link to anywhere, I don’t know what exactly is their objective, to encourage me to buy? I don’t think so, they don’t have a good marketing strategy.
However, there are 3 main advantages:

  • I feel to be important :-P As they made a robot especially for my form
  • They encourage me to focus more on development
  • They sometimes use a proxy server, so it makes an additional proxy address for me

Okay, Now I can estimate that I won. Certainly not the match, but at least, one round.
I have released the source code under GPL, feel free to hack on it, and if you break my security and find out how to spam me again, I will admit that you are a guru.
Source code may be download from here.
