for every one who dont have ssl in his hosting to use in facebook apps
i use this site

secure.social-server.com/facebook

- Create a new account.
- Put your url in and you'll have a secure link for your facebook apps

You can get your real free SSL from here - https://www.startssl.com/?app=0
You will get Class 1 certificate (domain or email validated). For personal use its pretty enough.

Just don't forget to save all certificates and keys on your computer.

Good luck.
