is a digital certificate ?
Digital
certificates (also called Secure Server IDs) are like virtual electronic
fingerprints. Each one is unique and can be used to positively identify the
person or object (e.g. a company's Internet server), who owns the certificate
by the information contained within it. That information can be trusted,
because it is digitally 'signed' by a trusted Certification Authority who
check the authenticity of the information to be included in the certificate
before they issue it. Digital Certificates provide the proof of identity and
deliver critical elements of security which are vital to establish the trust
needed to conduct safe communications and transactions with customers,
suppliers, partners and employees.

personal information using a fake email in order to commit identity theft,

you're not sure is from PayPal, make sure the address at the top of the
browser window you're brought to reads exactly www.paypal.com.
PayPal emails will address you by first name, last name, or business name, and
NOT by Dear PayPal User or Dear PayPal Member.
If you are ever uncertain about the validity of the email or the email links,
open a new web browser window and type in www.paypal.com.
