# Class IdentityScope

java.lang.Object
java.security.Identity
java.security.IdentityScope

All Implemented Interfaces:
  `Serializable, Principal`

@Deprecated(since="1.2", forRemoval=true) public abstract class IdentityScope extends Identity
Deprecated, for removal: This API element is subject to removal in a future version.
This class is deprecated and subject to removal in a future version of Java SE. It has been replaced by `java.security.KeyStore`, the `java.security.cert` package, and `java.security.Principal`.

This class represents a scope for identities. It is an Identity itself, and therefore has a name and can have a scope. It can also optionally have a public key and associated certificates.

An `IdentityScope` can contain `Identity` objects of all kinds, including signers. All types of `Identity` objects can be retrieved, added, and removed using the same methods. Note that it is possible, and in fact expected, that different types of identity scopes will apply different policies for their various operations on the various types of Identities.

There is a one-to-one mapping between keys and identities, and there can only be one copy of one key per scope. For example, suppose Acme Software, Inc is a software publisher known to a user. Suppose it is an Identity, that is, it has a public key, and a set of associated certificates. It is named in the scope using the name "Acme Software". No other named Identity in the scope has the same public key. Of course, none has the same name as well.

  1.1
