But In my case, I do not have any root certificate. I have only one signed certificate (SignedCertificate.pem) and one certificate signing request (certReq.pem) . So when I use it as below openssl verify -CAfile SignedCertificate.pem SignedCertificate.pem I am getting error "error 20 at 0 depth lookup:unable to get local issuer certificate". I believe it is for verifying certificate chain trust. Correct me if I am wrong. Is there anyway to manipulate it?
