Named constructor functions are also available, these are much faster than using new(): md5(), sha1(), sha224(), sha256(), sha384(), and sha512() More algorithms may be available on your platform but the above are guaranteed to exist. See the algorithms_guaranteed and algorithms_available attributes to find out what algorithm names can be passed to new(). NOTE: If you want the adler32 or crc32 hash functions they are available in the zlib module. Choose your hash function wisely. Some have known collision weaknesses. sha384 and sha512 will be slow on 32 bit platforms. Hash objects have these methods: - update(arg): Update the hash object with the string arg. Repeated calls are equivalent to a single call with the concatenation of all the arguments. - digest(): Return the digest of the strings passed to the update() method so far. This may contain non-ASCII characters, including NUL bytes. - hexdigest(): Like digest() except the digest is returned as a string of double length, containing only hexadecimal digits. - copy(): Return a copy (clone) of the hash object. This can be used to efficiently compute the digests of strings that share a common initial substring. For example, to obtain the digest of the string 'Nobody inspects the spammish repetition': >>> import hashlib >>> m = hashlib.md5() >>> m.update("Nobody inspects") >>> m.update(" the spammish repetition") >>> m.digest() '\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' More condensed: >>> hashlib.sha224("Nobody inspects the spammish repetition").hexdigest() 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' t md5t sha1t sha224t sha256t sha384t sha512t newt algorithms_guaranteedt algorithms_availablet algorithmst pbkdf2_hmacc C s y� | d k r" d d l } | j S| d k rA d d l } | j S| d k r� d d l } | d } | d k rv | j S| d k r� | j SnK | d k r� d d l } | d } | d k r� | j S| d k r� | j Sn Wn t k r� n Xt d | � � d S( Nt SHA1R i����t MD5R t SHA256R t SHA224R i t 256t 224t SHA512R t SHA384R t 512t 384s unsupported hash type ( R R ( R R ( R R R R ( R R R R ( t _shaR t _md5t _sha256R R t _sha512R R t ImportErrort ValueError( t nameR R R t bsR ( ( s /usr/lib/python2.7/hashlib.pyt __get_builtin_constructorH s0 c C sG y" t t d | � } | � | SWn t t f k rB t | � SXd S( Nt openssl_( t getattrt _hashlibt AttributeErrorR R ( R t f( ( s /usr/lib/python2.7/hashlib.pyt __get_openssl_constructord s t c C s t | � | � S( s| new(name, string='') - Return a new hashing object using the named algorithm; optionally initialized with a string.
