Provides the classes and interfaces for the security framework.
This includes classes that implement an easily configurable,
fine-grained access control security architecture.
This package also supports
the generation and storage of cryptographic public key pairs,
as well as a number of exportable cryptographic operations
including those for message digest and signature generation. Finally,
this package provides classes that support signed/guarded objects
and secure random number generation.
Many of the classes provided in this package (the cryptographic
and secure random number generator classes in particular) are
provider-based. The class itself defines a programming interface
to which applications may write. The implementations themselves may
then be written by independent third-party vendors and plugged
in seamlessly as needed. Therefore application developers may
take advantage of any number of provider-based implementations
without having to add or rewrite code.

REVISED This class extends ClassLoader with additional support for defining
classes with an associated code source and permissions which are
retrieved by the system policy by default.
