/**
 * 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.
