+ # 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..."
