It produces the 224 bit digest of a message. >>> from Crypto.Hash import SHA224 >>> >>> h = SHA224.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 s$Id$tnewt digest_sizet SHA224Hashi˙˙˙˙(t*(tHashAlgoN(t_SHA224cBs>eZdZedƒZdZdZdd„Zdd„Z RS(sLClass that implements a SHA-224 hash :undocumented: block_size s  `†Heii@cCstj|t|ƒdS(N(Rt__init__t hashFactory(tselftdata((s1lib/python2.7/site-packages/Crypto/Hash/SHA224.pyRGscCs t|ƒS(N(R(RR ((s1lib/python2.7/site-packages/Crypto/Hash/SHA224.pyRJsN( t__name__t __module__t__doc__tbtoidRt block_sizetNoneRR(((s1lib/python2.7/site-packages/Crypto/Hash/SHA224.pyR4s   cCstƒj|ƒS(s Return a fresh instance of the hash object. :Parameters: data : byte string The very first chunk of the message to hash.
