The security of your
information, transactions, and money is the core of our business and a
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). When you make a purchase on our site,
PayPals server checks that you're using an approved browser - one that uses SSL 3.0 or higher.
Once your information reaches PayPal, it resides on a server that is
heavily guarded both physically and electronically. PayPal servers sit
behind an electronic firewall and are not directly connected to the
internet, so your private information is available only to authorized
computers.
