// - openssl x509 -req -extfile server.cnf -days 9999 -passin "pass:password" -in server-csr.pem -CA ca-crt.pem -CAkey ca-key.pem -CAcreateserial -out server-crt.pem
// - openssl x509 -req -extfile client1.cnf -days 9999 -passin "pass:password" -in client1-csr.pem -CA ca-crt.pem -CAkey ca-key.pem -CAcreateserial -out client1-crt.pem

// Verify certificates:
// - openssl verify -CAfile ca-crt.pem server-crt.pem
// - openssl verify -CAfile ca-crt.pem client1-crt.pem
// - openssl verify -CAfile ca-crt.pem client2-crt.pem
// Conversion of client1-crt.pem to certificate.pfx: https://stackoverflow.com/a/38408666/4637638
