Description

A common set of Crypto Input/Output streams. They would be used by CryptoFileSystem, HDFS encryption, MapReduce intermediate data and spills. Note we cannot use the JDK Cipher Input/Output streams directly because we need to support the additional interfaces that the Hadoop FileSystem streams implement (Seekable, PositionedReadable, ByteBufferReadable, HasFileDescriptor, CanSetDropBehind, CanSetReadahead, HasEnhancedByteBufferAccess, Syncable, CanSetDropBehind).
