title: Verifying digital signatures on Mac Adobe Reader
body: <p>I'm attempting to sign PDFs with an SSL certificate issued from Go Daddy.</p>
  
  <p>These signatures show up as valid in the Windows Reader as long as you check the "Validating Signatures" check box under <code>Edit-&gt;Preferences...-&gt;Security-&gt;Advanced Preferences-&gt;Windows Integration-&gt;Trust ALL root certificates</code> in the Windows Certificate Store for the following operations.</p>
  
  <p>However, I can't seem to find a similar setting in the Mac OS X version of Reader.  Mac OS X appears to have something similar to the Windows Certificate Store in Keychain (specifically System Roots for Go Daddy).</p>
  
  <p>Is anyone aware of a setting on the Mac version that's similar to the Windows setting I mentioned?  If not, is there another PDF reader out there that would work for this scenario?</p>
