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. 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() 'dɡ' More condensed: >>> hashlib.sha224("Nobody inspects the spammish repetition").hexdigest() 'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2' cCs|djoddk}|iSn||djoddk}|iSnX|djoJddk}|d }|d jo |iSq|d jo |iSqntd dS(NtSHA1tsha1itMD5tmd5tSHA256tsha256tSHA224tsha224it256t224sunsupported hash type(Rssha1(sMD5smd5(Rssha256Rssha224(t_shatnewt_md5t_sha256RRt ValueError(tnameR R R tbs((s/sys/lib/python/hashlib.pyt__get_builtin_constructor7s             tcCst||S(s|new(name, string='') - Return a new hashing object using the named algorithm; optionally initialized with a string.
