- #
- # 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"
