Digital Certificates provide a means of proving your identity in electronic transactions; much like a driver license or a passport does in face-to-face interactions. With a Digital Certificate, you can assure friends, business associates, and online services that the electronic information they receive from you are authentic.
Digital Certificates, bind an identity to a pair of electronic keys that can be used to encrypt and sign digital information. A Digital Certificate makes it possible to verify someone's claim that they have the right to use a given key, helping to prevent people from using phony keys to impersonate other users. Used in conjunction with encryption, Digital Certificates provide a more complete security solution, assuring the identity of all parties involved in a transaction. A Digital Certificate is issued by a Certification Authority (CA) and signed with the CA's private key.
A Digital Certificate typically contains the:
Owner's public key
Owner's name
Expiration date of the public key
Name of the issuer (the CA that issued the Digital Certificate)
