+/**
+   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.
