title: SHA2 Support for Domino 8.5.3 FP6 Server?
body: <p>In this <a href="http://www-01.ibm.com/support/docview.wss?uid=swg21418982" rel="nofollow">technote</a> from IBM you can find the following answers:</p>
  
  <blockquote>
    <p><strong>Q1:</strong> Can I import the SHA-2 cert on a Domino 9.x server and then use that keyring on a Domino 8.5.x server? <strong>No.</strong> Domino 8.5.x lacks the
    cryptographic infrastructure for SHA-2. This means if you import the
    cert using 9.x and the Interim Fix and and KYRTool described above,
    you can use that keyring on a Domino 9.0 or above server, but not on a
    Domino server pre-Domino 9.0.</p>
    
    <p><strong>Q2:</strong> Can I get a hotfix on 8.5.x or earlier to support SHA-2?  <strong>No.</strong> This
    is not possible since releases prior to Domino 9.0 lack the
    cryptographic infrastructure for SHA-2.</p>
  </blockquote>
  
  <p>Is an update to <code>Domino 9.x</code> the only way the handle this issue? If so, how long it's time, before the relevant web browsers (ie, firefox and chrome) will cancel the support for SHA-1?</p>
