Chapter 19. javax.security.auth and Subpackages
This
chapter documents the
javax.security.auth
package and its subpackages,
which, together, form the Java
Authentication and Authorization Service, or JAAS. Before being
integrated into Java 1.4, JAAS was available as a standard extension,
which is why these packages have the
“javax” prefix. The individual
packages are the following:
-
javax.security.auth
This top-level package defines the
Subject
class that is central to JAAS.-
javax.security.auth.callback
This package defines a callback API to enable communication (such as the exchange of a username and password) between a low-level login module and the end-user.
-
javax.security.auth.kerberos
This package contains JAAS classes related to the Kerberos network authentication protocol.
-
javax.security.auth.login
This package defines the
LoginContext
class and related classes used by applications to perform a JAAS login.-
javax.security.auth.spi
This package defines the “service provider interface” for JAAS.
-
javax.security.auth.x500
This package includes JAAS classes related to X.500 principals.
