paypal button encryption

[jpearl]

Hi,
I have a store that is set up with the only payment method is paypal. However i do not have my own SSL certificate. i do have a shared ssl however, but it doesnt work when i try to use it to transfer the data from checkout to paypal. it just redirects the user to the homepage and never goes to paypal.
I've searched everywhere for a fix, but cannot seem to find one..

so i looked and on paypal's website it says something about securing your paypal buttons.... (here: https://www.paypal.com/IntegrationCenter/ic_button-encryption.html)

but i don't exactly understand what it wants me to do.

can someone please enlighten me?

thanks a ton
