I've created a new keystore with the keytool command and had given an alias of tomcat. I generated the CSR for sending to the CA to issue a certificate.
In the meantime, we've deleted the alias named tomcat from the keystore.
I fear this makes the certificate received from the CA now useless. As the alias which has been deleted contained the private key and/or associated link to the CSR.
I still have the keystore, and have created a new alias and change alias to the same name as originally used 'tomcat'. But I suspect this is not good, and I will now need to create an entire new keystore to create another CSR to request a new certificate.
Any help please, I do not have much experience with keystores as you can imagine.
