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.

Support for encryption includes symmetric, asymmetric, block,
and stream ciphers. This package also supports secure streams and
sealed objects.

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.
