title: Java encryption frameworks/toolkits
body: <p>My team is looking for a proven and easy to use Java encryption framework or toolkit to encrypt our data traffic.  We have found Google's <a href="http://www.keyczar.org/" rel="nofollow">KeyCzar</a> and it looks promising but we want to know if anyone has had success with other toolkits or have had issues with KeyCzar.</p>
