title: Free Encryption library for Delphi
body: <p>I'm looking for a free and up to date encryption library for Delphi 2010 that implements RSA and AES (Rijndael).</p>
  
  <p>I want a free library because I plan to write and publish some sample code that will use it.</p>
  
  <p>A Delphi 2010 version of TurboPower LockBox has been posted to the <a href="http://www.songbeamer.com/delphi/" rel="noreferrer">SongBeamer</a> site, that implements both of these, but I'm concerned that it's getting a little old.  For example, small RSA key sizes and no new security features for many years.</p>
  
  <p><strong>Update:</strong>
  Is the perception that LockBox is out of date or lacks important features incorrect?  Is it still relevant for production development?  (Particularly the RSA key sizes)</p>
