- The Certificate Class

This section describes the certificate class:, which represents a signed certificate of a public key.

In the previous chapter, I learned that the "keytool" command line tool can be used to manage certificates stored in "keystore" files. Now I want to learn how to use and classes to manage certificates stored in "keystore" files. is an abstract class representing common features of different implementations of different certificate types. Its main methods are:

In JDK, there is a deprecated interface named as Certificate under a different package, To help the compiler to take the correct class definition, I think I should use the full class name,, in my Java programs.
