intente generar una firma usando HMACSHA512 en C#

firma en c# usando HMACSHA512 no equivalente a java y JavaScript. después de rastrear mi código C #, encontré que la clave no se usa durante la generación de la firma.

 using System.Security.Cryptography; using System.Text; string privateKey = "OPAYPRV16388855997950.6319778282304234"; string message = "{\r\n \"country\": \"EG\",\r\n \"reference\": \"9cf357a79ffc4cb5a57cd0489a1a4bfa\"\r\n}"; byte[] messagebyte = Encoding.Default.GetBytes(message); byte[] pkey = Encoding.Default.GetBytes(privateKey); HMACSHA512 hMACSHA512 = new HMACSHA512(pkey); //hMACSHA512.Key = pkey; //other way and not give right signature //hmacsha512.Initialize(); var hmac = hMACSHA512.ComputeHash(messagebyte); var hmacres = BitConverter.ToString(hmac).Replace("-", ""); Console.WriteLine(hmacres); // signature c# =FC96AABB47DE439A78CB98943BA3E9F9C25B24264E1431CC4180348F5B48C869F9003E3B67B8E387D25A7189093ACDD90205A103A489856379971EBE07E295E5 // signature in java and JavaScript (the same and the right signature)= 20c8b06951a7907b48db0ccb0b1fb514e8addb2b7c72786cc21316576d57e57560188cac837ffe232a9b24e65e73c6c05e6a5dddff3cc03e26521c92e74e064d

HMACSHA512 trata con \r\n y espacios como caracteres, cuando eliminé /r/n y espacio obtuve la firma correcta

mensaje= mensaje.Reemplazar(Sistema.Entorno.NuevaLínea, cadena.Vacío).Reemplazar(" ", "");

byte[] mensajebyte = Codificación.Predeterminado.GetBytes(mensaje);

byte[] pkey = Codificación.Default.GetBytes(privateKey);

HMACSHA512 hMACSHA512 = nuevo HMACSHA512(pkey);

var hmac = hMACSHA512.ComputeHash(mensajebyte);

var hmacres = BitConverter.ToString(hmac).Replace("-", "");
