Digital Certificates are digital documents attesting to the binding of a public key to an individual or specific entity. They allow verification of the claim that a specific public key does in fact belong to a specific individual. Digital Certificates help prevent someone from using a phony key to impersonate someone else.

In their simplest form, certificates contain a public key and a name. As commonly used, a certificate also contains an expiration date, the name of the Certifying Authority that issued the certificate, a serial number etc. Most importantly, it contains the digital signature of the certificate issuer.
