<p style="color: grey"> Python recipe 578838 by <a href="/recipes/users/4186880/">Andrea Corbellini</a> (<a href="/recipes/tags/encryption/">encryption</a>, <a href="/recipes/tags/learning/">learning</a>, <a href="/recipes/tags/rsa/">rsa</a>, <a href="/recipes/tags/security/">security</a>). </p> <p>This is a really simple RSA implementation. It does not want to be neither fast nor safe; it's aim is to provide a working and easy to read codebase for people interested in discovering the RSA algorithm.</p>

Revision 4. </p> <p>This module provides classes that are useful for executing Markov encryption and decryption on data. ME was inspired by a combination of Markov chains with the puzzles of Sudoku. This implementation is a rewrite from the Python 3.x version and includes various changes and optimizations to work with Python 2.5 and related versions. All documentation has been left in <a href="http://code.activestate.com/recipes/578075/">recipe 578075</a> and should be referred to there.</p>
