Hi, I am trying to create a ECC certificate with ecdsa_with_SHA3-512 signature algorithm. But I am having the below issue When I try to verify it with the X509_Verify api. "error:068000C7:asn1 encoding routines::unknown signature algorithm" As I understand, "ecdsa_with_SHA3-512" signature nid has

Thanks. I did some more analysis and now I understand it completely. ECC curve equation: y^2 = x^3 + ax + b (mod p), where p is prime Elliptic Curve parameters are: p, a, b, G, n, h G = Generator Point used to generate other points Private Key = Random Number Public Key = Point on Curve = (Genera
