What Is A Digital Certificate?

What Is A Digital Certificate?

A digital certificate is an electronic “credit card” that establishes your credentials when doing business or other transactions on the Web. It is issued by a Certification Authority (CA).

It contains your name, a serial number, expiration dates, a copy of the certificate holder’s public key (used for encrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real.

Some digital certificates conform to a standard, X.509. Digital certificates can be kept in registries so that authenticating users can look up other users’ public keys.
