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.
