-/**
- The Identity class is used to repsent people and companies that
- can be authenticated using public key encryption. The identities
- can also be abstract objects such as smart cards.
-
- Identity object store a name and public key for each identity.
- The names cannot be changed and the identities can be scoped.
- Each identity (name and public key) within a scope is unique
- to that scope.
-
- Each identity has a set of ceritificates which all specify the
- same public key but not necessarily the same name.
-
- The Identity class can be subclassed to allow additional
- information to be attached to it.
-
- @since JDK 1.1
-
- @deprecated Use java.security.KeyStore, the java.security.cert
- package, and java.security.Principal.
