title: Tomcat / JKS / Keytool - regenerate private key?
body: <p>Is it possible to regenerate a private key in a .JKS keystore using keytool or equivalent?</p>
  
  <p>I've been supplied with a certificate and a JKS keystore, but on importing the cert it looks like the private key that was used to generate the CSR has been deleted.</p>
  
  <p>I can see how to create a new keystore with a new private key, but this won't then match the CSR or certificate.</p>
