Nobody can forge certificates because the CA digitally signs the certificates and the signature is applied to a hash of the certificate. The entities that issue and manage digital certificates are called certificate authorities (CAs). A digital certificate associates a public key with an entity such as an individual or organization because it contains the public key for the user or organization, additional information on the user or organization, and information on the entity that issued the certificate. Only the private key in the key pair can decrypt the data to a readable format.Äigital certificates distribute the public key. The public key encrypts the data into an unreadable or scrambled format. The public and private key pair encrypts and decrypts data. In public key encryption, each user has a private key that is kept secret and is never sent over the network and a public key that can be publicly distributed. Encryption is used to protect data messages as they are transmitted over the network and digital signatures verify the identities of these messages’ senders. A public key infrastructure is the collection of technology, protocols, services, standards, and policies that control the issuing and management of public and private keys using digital certificates. The Windows 2000 and Windows Server 2003 PKI implementation resides in Certificate Services. While encryption can be a robust security technology, users have to implement a public key infrastructure (PKI) to make it beneficial and trusted within an organization.
