Q:

Is it possible to install existing private key and ssl certificate in a new keystore?

We have lost our original keystore used to generate the CSR during a server failure. We have a backup of the private key (.key file) and the original CSR (.csr file). Is it possible to reconstruct the keystore with those? Since all the instructions for creating the certificate chains require the original keystore.
This is for use with Tomcat 7.0.27.
Thanks

A:

Yes, that should be possible. But in addition to the private key you will also need the certificate (not csr) that was returned by the CA. The steps can be found here

A:

Seems the only way we got it working properly was to revoke our existing certificate and renew it with a new CSR.
