Verify error:num=20:unable to get local issuer certificate Setting the flags for the certificate store is very important. Ive created two self signed certificates for testing which only differ in that one has a CA flag (ss-ca.pem) while the other does not (ss-noca.pem).With openssl verify one can check if the certificate can be verified against a specific CA path.
