The security of your information, transactions, and money is the core of our
business and our top priority at PayPal.
PayPal automatically encrypts
your confidential information in transit from your computer to ours using the
Secure Sockets Layer protocol (SSL) with an encryption key length of 128-bits
(the highest level commercially available). Before you even register or log in
to our site, our server checks that you're using an approved browser - one that
uses SSL 3.0 or higher.
Once your information reaches us, it resides on a
server that is heavily guarded both physically and electronically. Our servers
sit behind an electronic firewall and are not directly connected to the
internet, so your private information is available only to authorized
computers.
