It produces the 256 bit digest of a message. >>> from Crypto.Hash import SHA256 >>> >>> h = SHA256.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 SHA256Hashiÿÿÿÿ(t*(tHashAlgoN(t_SHA256cBs>eZdZedƒZdZdZdd„Zdd„Z RS(sLClass that implements a SHA-256 hash :undocumented: block_size s  `†Hei i@cCstj|t|ƒdS(N(Rt__init__t hashFactory(tselftdata((s8/usr/lib64/python2.7/site-packages/Crypto/Hash/SHA256.pyRGscCs t|ƒS(N(R(RR ((s8/usr/lib64/python2.7/site-packages/Crypto/Hash/SHA256.pyRJsN( t__name__t __module__t__doc__tbtoidRt block_sizetNoneRR(((s8/usr/lib64/python2.7/site-packages/Crypto/Hash/SHA256.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.
