A Digital Certificate is an electronic “password” that allows a person, organization to exchange data securely over the Internet using the public key infrastructure. In other words a digital certificate is an electronic password that authenticates and verifies a device or user.
A digital certificate primarily acts like an identification card; something like a driver’s license, a passport, a company ID, or a school ID.
A digital certificate is an electronic document issued by a Certificate Authority (CA). It contains the public key for a digital signature and specifies the identity associated with the key, such as the name of an organization.
The main purpose of the digital certificate is to ensure that the public key contained in the certificate belongs to the entity to which the certificate was issued, in other words, to verify that a person sending a message is who he or she claims to be, and to then provide the message receiver with the means to encode the message .
There are actually two more types of certificates: code-signing and user/client certificates, which are equally important to securing our online communications.
