Built-in module md5

md5

This module implements the interface to RSA's MD5 message digest algorithm (see also the file md5.doc). It's use is very straightforward: use the function md5 to create an md5-object. You can now ``feed'' this object with arbitrary strings.

At any time you can ask the ``final'' digest of the object. Internally, a temorary copy of the object is made and the digest is computed and returned. Because of the copy, the digest operation is not desctructive for the object. Before a more exact description of the use, a small example: to obtain the digest of the string 'abc', use ... 

>>> from md5 import md5
>>> m = md5()
>>> m.update('abc')
>>> m.digest()
'\220\001P\230<\322O\260\326\226?}(\341\177r'

More condensed: 

>>> md5('abc').digest()
'\220\001P\230<\322O\260\326\226?}(\341\177r'


\begin{funcdesc}{md5}{arg} Create a new md5-object. \var{arg} is optional: if p... ...itial \code{update} method is called with \var{arg} as argument. \end{funcdesc}

An md5-object has the following methods:


\begin{funcdesc}{update}{arg} Update this md5-object with the string \var{arg}. \end{funcdesc}


\begin{funcdesc}{digest}{} Return the \dfn{digest} of this md5-object. Internal... ...ction \code{MD5Final} is called. Finally the digest is returned. \end{funcdesc}


\begin{funcdesc}{copy}{} Return a separate copy of this md5-object. An \code{update} to this copy won't affect the original object. \end{funcdesc}
