Привет, я пытаюсь зашифровать RSA со своей собственной N public, но я всегда получаю неверный размер ключа длины.вот мой код; 

using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates; 

byte[] PublicKey =   {0x91,0xC7,0x3E,0xF8,0xBC,0x5E,0x99,0x28,0xF2,0x3C,0x5B,0x3B,0x2B,0x5B,0x59,0x0D,0x1F,0xB7,0x01,0xC5,0x3E,0xA1,0xCE,0x3B,0xC1,

                        0x86,0x3F,0x2C,0x40,0x6C,0xFA,0x50,0x67,0x65,0xBA,0x31,0x23 };
    byte[] Exponent = { 1, 0, 1 };

    byte[] encrypted = {0x3D,0x7E,0x2F,0x95,0x21,0x73,0x75,0x28,0x4A,0x37,0x5C,0xAB,0x82,0x2B,0xAD,0x6A,0xCD,0x2E,0x60,0x96,0x61,0xEB,0x41,0xD6,0x6D,

static byte[] Encrypt(byte[] input, RSAParameters RSAKeyInfo, bool DoOAEPPadding)
    {
        byte[] encrypted;
        using (var RSA = new RSACryptoServiceProvider(896))
        {
            RSA.ImportParameters(RSAKeyInfo);
            encrypted = RSA.Encrypt(input, DoOAEPPadding);
        }
        return encrypted;
    }

RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
RSAParameters RSAKeyInfo = new RSAParameters();
RSAKeyInfo.Modulus = PublicKey;
RSAKeyInfo.Exponent = Exponent;

RSA.ImportParameters(RSAKeyInfo);
var pubKey = RSA.ExportParameters(false);
byte[] encrypted2 = Encrypt(encrypted, pubKey, false);

ключ и данные для шифрования имеют одинаковые len 112 байт, любая помощь?
