+Provides the classes and interfaces for cryptographic operations. The
+cryptographic operations defined in this package include encryption,
+key generation and key agreement, and Message Authentication Code
+(MAC) generation.
+
+<p>Support for encryption includes symmetric, asymmetric, block, and
+stream ciphers. This package also supports secure streams and sealed
+objects.
+
+<p>Many of the classes provided in this package 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.
