Android数据加密，适配.net RSACryptoServiceProvider Encrypt方法

[Bense1999]

C#代码加密方法如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using System.Threading.Tasks;

namespace WindowsFormsApplication1
{
    public static class Helper
    {
        public static byte[] EncryptData(byte[] data, string certificateFilePath)
        {
            X509Certificate2 cert = new X509Certificate2(certificateFilePath);
            RSACryptoServiceProvider provider = new RSACryptoServiceProvider();
            //转码 
            //获取公钥,公钥加密,私钥解密, 数据库就是通过私钥解密,所以这里需要获取公钥进行加密, 
            string keyPublic = cert.PublicKey.Key.ToXmlString(false);
            provider.FromXmlString(keyPublic);
            //加密方法 
            byte[] by = provider.Encrypt(data, false);
            //反转一维 Array 或部分 Array 中元素的顺序,这个无论加密解密必须得有否则失败 
            Array.Reverse(by);

            return by;
        }

        public static string ByteToHexStr(byte[] bytes)
        {
            string returnStr = "";
            if (bytes != null)
            {
                for (int i = 0; i < bytes.Length; i++)
                {
                    returnStr += bytes[i].ToString("X2");
                }
            }
            return returnStr;
        }
    }
}

MSSQL加密解密代码：

CREATE MASTER KEY ENCRYPTION BY PASSWORD = '****'
go
 
--DROP MASTER KEY
 
create certificate HKGT0501T
from file = 'D:\Projects\MFM\HKGT0501T.cer'
with private key
(file = 'D:\Projects\MFM\HKGT0501T.pvk',decryption by password ='***')
go
--卡号加密
CREATE PROCEDURE [dbo].[up_EncryptCardNumber]
	@CardNo VARCHAR(MAX)
AS
BEGIN

	DECLARE @EncryptedValue VARCHAR(MAX)
	SELECT @EncryptedValue= CONVERT(VARCHAR(MAX),EncryptByCert(Cert_ID('HKGT0501T'), @CardNo),2)
	
	SELECT @EncryptedValue AS EncryptedValue
END
go

--卡号解密
CREATE PROCEDURE [dbo].[up_DecryptData]
	@DataIn VARBINARY(128),
	@DataOut VARBINARY(128)=NULL OUT
AS
BEGIN
	SET @DataOut=DECRYPTBYCERT(Cert_ID('HKGT0501T'),@DataIn)
END
go

有哪位大神知道该加密算法对应的Android代码？
本人试过以下加密算法，但用MSSQL解密失败

public static String generateTCSRSAPassword(String certificateFilePath, String password) {
        PublicKey tcsPublicKey = null;
        try {
            tcsPublicKey = getPublicKeyFromX509(certificateFilePath);
            if (tcsPublicKey != null) {
                Cipher tcsCipher = Cipher.getInstance(tcsPublicKey
                        .getAlgorithm());
                tcsCipher.init(Cipher.ENCRYPT_MODE, tcsPublicKey, new SecureRandom());
                String tcsEncryptPassword = bytesToHexString(tcsCipher
                        .doFinal(android.util.Base64.encode(password.getBytes(), android.util.Base64.DEFAULT)));
                return tcsEncryptPassword;
            } else {
                //log.warn(ENCRPTY_FILE_NAME + " cannot be found!");
                //throw new Exception(ENCRPTY_FILE_NAME + " cannot be found!");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

    public static String bytesToHexString(byte[] src){
        StringBuilder stringBuilder = new StringBuilder("");
        if (src == null || src.length <= 0) {
            return null;
        }
        for (int i = 0; i < src.length; i++) {
            int v = src[i] & 0xFF;
            String hv = Integer.toHexString(v);
            if (hv.length() < 2) {
                stringBuilder.append(0);
            }
            stringBuilder.append(hv);
        }
        return stringBuilder.toString();
    }

    private static PublicKey getPublicKeyFromX509(String certificateFilePath)
            throws Exception {
        File file=new File(certificateFilePath);
        InputStream fin = new FileInputStream(file);
        CertificateFactory f = CertificateFactory.getInstance("X.509");
        X509Certificate certificate = (X509Certificate) f
                .generateCertificate(fin);
        PublicKey pk = certificate.getPublicKey();
        return pk;
    }
