A digital certificate is an electronic "passport" that authenticates a web site
when doing business or other transactions on the Web. It is issued by a
certification authority (viz Comodo, Verisign). It contains, amongst other
things, the name,a serial number, expiration datesand the digital signature of
the certification authority, so that a recipient can verify that the certificate
is genuine. You can verify a digital certificate by clicking (or
double-clicking) on the closed padlock that comes up at the bottom of the
browser when doing business with a secure web site.
Secure Digital Certificates allow you to encrypt and digitally
sign email and attachments keeping them secure and confidential:

8 Digitally Sign your emails to ensure that the
message and attachments cannot be tampered with en route via the
Internet without the recipient being alerted to the tampering.
