# A meta digest provider class for SHA256, SHA384 and SHA512.
#
# FIPS 180-2 describes SHA2 family of digest algorithms. It defines
# three algorithms:
# * one which works on chunks of 512 bits and returns a 256-bit
#   digest (SHA256),
# * one which works on chunks of 1024 bits and returns a 384-bit
#   digest (SHA384),
# * and one which works on chunks of 1024 bits and returns a 512-bit
#   digest (SHA512).
#
# ==Examples
#  require 'digest'
#
#  # Compute a complete digest
#  Digest::SHA2.hexdigest 'abc'          # => "ba7816bf8..."
#  Digest::SHA2.new(256).hexdigest 'abc' # => "ba7816bf8..."
#  Digest::SHA256.hexdigest 'abc'        # => "ba7816bf8..."
#
#  Digest::SHA2.new(384).hexdigest 'abc' # => "cb00753f4..."
#  Digest::SHA384.hexdigest 'abc'        # => "cb00753f4..."
#
#  Digest::SHA2.new(512).hexdigest 'abc' # => "ddaf35a19..."
#  Digest::SHA512.hexdigest 'abc'        # => "ddaf35a19..."
#
#  # Compute digest by chunks
#  sha2 = Digest::SHA2.new               # =>#<Digest::SHA2:256>
#  sha2.update "ab"
#  sha2 << "c"                           # alias for #update
#  sha2.hexdigest                        # => "ba7816bf8..."

#  # Use the same object to compute another digest
#  sha2.reset
#  sha2 << "message"
#  sha2.hexdigest                        # => "ab530a13e..."
