<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 2. </p> <p>As you display message on a web page, you have to sanitize input data coming from users to avoid <a href="https://en.wikipedia.org/wiki/Cross-site_scripting">XSS</a>. Here is a small recipe where we can use a special class for our string to be sure we get safe all the way long.</p>

Revision 2. </p> <p>This recipe generates a pseudo-random password of a prescribed length. It also lets you specify what characters are not permitted in the password or specify what characters are.</p>

Revision 2. </p> <p>I think this script should now be functional enough to post here at ActiveState. When you reply or vote down, please post some information on your problem with the code, and if you can, maybe something about the solution. This interface works, and is designed especially for Python. If you like it, don't be afraid to post that either, constructive criticism is all good, but compliments are even better! ;)</p> <p>Get the latest version of this code here: <a href="http://wiki.sunjay.ca/Python:Contents/Python_Session" rel="nofollow">http://wiki.sunjay.ca/Python:Contents/Python_Session</a></p> <p><strong>Latest Changes:</strong></p> <ul> <li>Added a new function for making the session cookie last longer. See code for <code>set_expires</code>. Note: This new function is just in case you need to include a session for longer than one brower session (for example, one day instead). </li> </ul>

Revision 3. </p> <p>Because I did not want to expose my passwords in plain text whenever an exception was thrown or inside the debugger, I wrote this simple snippet. It's very simple, but can be quite useful nonetheless...</p>
