It produces the 512 bit digest of a message. >>> from Crypto.Hash import SHA512 >>> >>> h = SHA512.new() >>> h.update(b'Hello') >>> print h.hexdigest() *SHA* stands for Secure Hash Algorithm. .. _SHA-2: http://csrc.nist.gov/publications/fips/fips180-2/fips180-2.pdf z$Id$ÚnewÚ digest_sizeÚ SHA512Hashé)Ú*)ÚHashAlgoN)Ú_SHA512c@s4eZdZdZedƒZdZdZd dd„Zd dd „Z dS) rzLClass that implements a SHA-512 hash :undocumented: block_size u  `†Heé@é€NcCst |t|¡dS)N)rÚ__init__Ú hashFactory)ÚselfÚdata©rú1lib/python3.7/site-packages/Crypto/Hash/SHA512.pyr GszSHA512Hash.__init__cCst|ƒS)N)r)r r rrrrJszSHA512Hash.new)N)N) Ú__name__Ú __module__Ú __qualname__Ú__doc__ÚbZoidrÚ block_sizer rrrrrr4s   cCs tƒ |¡S)a Return a fresh instance of the hash object. :Parameters: data : byte string The very first chunk of the message to hash.
