You should use SHA-2 for all of your certs. Everyone should have switched to that years ago. :( yes. There may be a corner case, though. The root cert itself is not signed by anyone, of course. I.e. technically, it's a self-signed cert. If you have an SHA-1 signature part here, no security issue will arise, but some TLS exchanges will break nevertheless. We had this issue during a short period when we had started re-issuing all certs with SHA-256 signatures except for the root cert itself.
