4.5 Certificate
In cryptography, a public key certificate (also known as a digital certificate or identity certificate) is an electronic document
used to prove ownership of a public key. The certificate includes information about the key, information about its owner's
identity, and the digital signature of an entity that has verified the certificate's contents as genuine. If the signature is valid,
and the person examining the certificate trusts the signer, then they know they can use that key to communicate with its
owner.
In a typical public-key infrastructure (PKI) scheme, the signer is a certificate authority (CA), usually a company such as
VeriSign™ which charges customers to issue certificates for them. In a web of trust scheme, the signer is either the key's
owner (a self-signed certificate) or other users ("endorsements") whom the person examining the certificate might know and
trust.
Certificates are an important component of Transport Layer Security (TLS, also known by its older name SSL), where they
prevent an attacker from impersonating a secure website or other server. They are also used in other important applications,
such as email encryption and code signing or in IPSec tunnelling for user authentication.
