title: Is there a way to get validity (notAfter) from a openssl certificate fingerprint and no certificate?
body: <p>Is there a way I can determine when a particular certificate fingerprint without having the certificate itself?</p>
  <p>something like
  <code>OpenSSL::X509::Certificate.new(&quot;-----BEGIN CERTIFICATE-----\n&quot;+cert+&quot;\n-----END CERTIFICATE-----\n&quot;)</code> but from a certificate fingerprint?</p>
  <p>background: i've authentication being done using this certificate and end users are allowed to input either certificate or its fingerprint to enable authentication from my side</p>
