How to recover ca.key on OpenVPN server?

Question

openvpn

There is an OpenVPN server and there is a ca.crt certificate. The key ca.key got lost. Tell me how to generate a new key with the old certificate so that you can generate keys and use the old ca.crt on the server. It is impossible to change ca.crt on clients (((

Answer 1

no way. because the certificate is available to the client, but the key is not.
if it were possible to generate a private key from a public certificate, then there would be no point in using encryption.
