Certificate
A certificate is related to public key algorithms. It authenticates the public key in an asymmetric transfer. It is used
to counteract usurpation by an attacker that substitutes the right public key by his own key. A certificate consists in
the public key signed by a certificate authority (CA) private key. This CA is considered as fully trusted.
In addition to the public key, the certificate also contains version numbers, validity period and some IDs.
