Description: 
        What Does Simple Crypt Do?
        --------------------------
        
        Simple Crypt encrypts and decrypts data.  It has two functions, ``encrypt``
        and ``decrypt``::
        
            from simplecrypt import encrypt, decrypt
            ciphertext = encrypt('password', plaintext)
            plaintext = decrypt('password', ciphertext)
        
        That's it.  You can see the implementation on
        `github <https://github.com/andrewcooke/simple-crypt/blob/master/src/simplecrypt/__init__.py>`_.
        
        Why Should I Use Simple Crypt?
        ------------------------------
        
        * It uses standard, well-known algorithms, closely following the
          recommendations `here
          <http://www.daemonology.net/blog/2009-06-11-cryptographic-right-answers.html>`_.
        
        * The established, efficient `pycrypto <https://www.dlitz.net/software/pycrypto>`_
          library provides the algorithm implementations (the cipher used is AES256).
        
        * It includes a check (an HMAC with SHA256) to warn when ciphertext
          data are modified.
        
        * It tries to make things as secure as possible when poor quality
          passwords are used (PBKDF2 with SHA256, a 256 bit random salt
          (increased from 128 bits in release 3.0.0), and 100,000 rounds
          (increased from 10,000 in release 4.0.0)).  But that doesn't mean
          you should use a poor password!
        
        * Using a library, rather than writing your own code, means that we
          have less solutions to the same problem.  That means more chance of
          finding bugs, which means more reliable, more secure code.
        
        * If simple-crypt does have a bug, the use of a header in the
          ciphertext data will help support an upgrade path (I can't promise
          full backwards support, because any solution will depend on the
          attack, but at least the needed information is present).
        
        What Else Should I Know?
        ------------------------
        
        * You must also install ``pycrypto``.  **Note** that pycrypto has
          parts written in C so requires a full python install.  On some unix
          systems that may mean adding a package like ``python-dev`` from your
          package manager.
        
        * In Python 3 the outputs from ``encrypt`` and ``decrypt`` are
          ``bytes``.  If you started with string input then you can convert
          the output from ``decrypt`` using ``.decode('utf8')``.
        
        ::
        
            mystring = decrypt('password', ciphertext).decode('utf8')
        
        
        * Later versions *can* decrypt data from previous versions, but data
          encrypted by later (major) versions *cannot* be decrypted by earlier
          code (instead, an error is raised asking the user to update to the
          latest version).
