title: Will public thumbprint change on renewing a certificate?
body: <p>I have a certificate for one year with PublicKey A, and ThumbPrint B.
  As long as I know, the ThumbPrint is generated by a hash algorithm from A.</p>
  
  <p>If I regenerate the certificate again with PublicKey A, the ThumbPrint should not change and will be B, right?</p>
  
  <p>Regards.</p>
