This deprecated class was used in Java 1.1 to represent an entity or Principal that has an associated PrivateKey that enables it to create digital signatures. As of Java 1.2, this class and the related Identity and IdentityScope classes have been replaced by KeyStore and java.security.cert.Certificate. See also Identity.
