/**
|
|
|
|
The Certificate class is an abstract class used to manage
|
|
|
|
identity certificates. An identity certificate is a
|
|
|
|
combination of a principal and a public key which is
|
|
|
|
certified by another principal. This is the puprose of
|
|
|
|
Certificate Authorities (CA).
|
|
|
|
|
|
|
|
This class is used to manage different types of certificates
|
|
|
|
but have important common puposes. Different types of
|
|
|
|
certificates like X.509 and OpenPGP share general certificate
|
|
|
|
functions (like encoding and verifying) and information like
|
|
|
|
public keys.
|
|
|
|
|
|
|
|
X.509, OpenPGP, and SDSI can be implemented by subclassing this
|
|
|
|
class even though they differ in storage methods and information
|
|
|
|
stored.
