title: CDSA deprecated in OS X Lion. What replaces it?
body: <p>I just read that <a href="http://lists.apple.com/archives/fed-talk/2011/Jul/msg00099.html" rel="nofollow">CDSA is deprecated in OS X 10.7</a>.</p>
  
  <p>What is the recommended replacement?</p>
  
  <p>I am especially interested in the plugin framework: what is the new way to implement access to smartcards etc.? Tokend is deprecated now: what does Mail and Safari use to access private keys?</p>
