Why rsaKey.PublicKey == rsaKey.PrivateKey

[dev-ptdi]

Hi..

Why rsaKey.PublicKey == rsaKey.PrivateKey

var rsaKey = EncryptProvider.CreateRsaKey(RsaSize.R4096);

        string _publicKey = rsaKey.PublicKey;
        JObject _jo_public_key = JObject.Parse(_publicKey);
        string _public_key = (string)_jo_public_key["Modulus"];

        var _privateKey = rsaKey.PrivateKey;
        JObject _jo_private_key = JObject.Parse(_privateKey);
        string _private_key = (string)_jo_private_key["Modulus"];

The modulus same don't mean the privateKey equal publickKey.

  internal static string ToJsonString(this RSA rsa, bool includePrivateParameters)
        {
            RSAParameters parameters = rsa.ExportParameters(includePrivateParameters);

            var parasJson = new RSAParametersJson()
            {
                Modulus = parameters.Modulus != null ? Convert.ToBase64String(parameters.Modulus) : null,
                Exponent = parameters.Exponent != null ? Convert.ToBase64String(parameters.Exponent) : null,
                P = parameters.P != null ? Convert.ToBase64String(parameters.P) : null,
                Q = parameters.Q != null ? Convert.ToBase64String(parameters.Q) : null,
                DP = parameters.DP != null ? Convert.ToBase64String(parameters.DP) : null,
                DQ = parameters.DQ != null ? Convert.ToBase64String(parameters.DQ) : null,
                InverseQ = parameters.InverseQ != null ? Convert.ToBase64String(parameters.InverseQ) : null,
                D = parameters.D != null ? Convert.ToBase64String(parameters.D) : null
            };

            return JsonConvert.SerializeObject(parasJson);
        }
