Class CCertificate

class CCertificate : public CSignedObject;

Description

A data structure that binds a public key to a given individual.

A certificate is a signed object, and adds a serial number, a validity period and a subject public key.

This is a base class for classes that implement certificates of particular types.

Derivation

• CBase - Base class for all classes to be instantiated on the heap.

• CSignedObject - Base class for certificates.

• CCertificate - A data structure that binds a public key to a given individual.
