c# RSA 只提供公钥 Exponent Modulus 怎么进行加密

c# RSA 只提供公钥 Exponent Modulus 如何进行加密？
如题所示， Exponent长度是多少 他们提供给我的值分别如下
公钥 "010001" M是 modulus

E130E28FA4D3D6A57ECA8422A482E22C5E0BA67434160B95A68DF  
怎么利用自带的类去实现加密呢
 RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
 RSAParameters para = new RSAParameters();

"010001"是3个字节。exponent和modulus正好提供了一个公钥（只能用来加密）。

C# code

class Program{    static void Main(string[] args)    {        string exponent = "010001";        string modulus =             "A3A69317FB92A534912A0999A7EEE826358C05F434C5E1E" +            "DB61C68E882CE52F7573FA44CE46E858673A8A328E17712F" +            "DAAECF383F13ECC1FD9D1505D2F23C983AD36F951788DEE30F1A" +            "E2A34F2DB13E46C409980A5467E05C7667AAD896464ABB073AA01AAF" +            "E130E28FA4D3D6A57ECA8422A482E22C5E0BA67434160B95A68DF";                    RSAParameters rsaParameters = new RSAParameters()        {            Exponent = FromHex(exponent), // new byte[] {01, 00, 01}            Modulus = FromHex(modulus),   // new byte[] {A3, A6, ...}        };        RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();        rsa.ImportParameters(rsaParameters);        byte[] sample = rsa.Encrypt(Encoding.UTF8.GetBytes("hello world"), false);    }    static byte[] FromHex(string hex)    {        if (string.IsNullOrEmpty(hex) || hex.Length % 2 != 0) throw new ArgumentException("not a hexidecimal string");        List<byte> bytes = new List<byte>();        for (int i = 0; i < hex.Length; i += 2)        {            bytes.Add(Convert.ToByte(hex.Substring(i, 2), 16));        }        return bytes.ToArray();    }}

试试这个：
RSAParameters Exponent 是三个字节，一般固定是0x01, 0, 0x01

byte[] plainData = new byte[117];// 明文数据;
RSACryptoServiceProvider rsaPub = new RSACryptoServiceProvider();
RSAParameters rparam = new RSAParameters();
rparam.Modulus = mods;
rparam.Exponent = new byte[] { 1, 0, 1 };
rsaPub.ImportParameters(rparam);
byte[] enData = rsaPub.Encrypt(plainData, false);
