C#实现标准JAVA的Md5withRsa算法

确认可行的方法
public static String pfxpath = @"E:\xxx.pfx";
public static String cerpath = @"E:\xxxx.cer";
public static String pfxpassword = "111111";

/// <summary>
/// 签名
/// </summary>
/// <param name="xml">xml数据</param>
/// <returns>签名数据</returns>
public static String signData(String xml)
{
Console.WriteLine("加载数字证书私钥："+ pfxpath + "证书密码：" + pfxpassword);
//签名
Console.WriteLine("--------开始使用私钥创建例子");
Console.WriteLine("--------需要签名的：" + xml);
// X509Certificate2 objx5092 = new X509Certificate2(pfxpath, pfxpassword); //当前用户存储，本地测试
X509Certificate2 objx5092 = new X509Certificate2(pfxpath, pfxpassword,X509KeyStorageFlags.MachineKeySet); //本地存储，服务器测试(windows server2008)要使用这个

RSACryptoServiceProvider rsa = objx5092.PrivateKey as RSACryptoServiceProvider;
byte[] data = Encoding.GetEncoding("GBK").GetBytes(xml);
byte[] hashValue = rsa.SignData(data, "MD5");
string msg = Convert.ToBase64String(hashValue);
Console.WriteLine("--------得到：" + msg);

return msg;
}

///
/// 解签
/// </summary>
/// <param name="signData">解签数据</param>
/// <returns>是否成功</returns>
public bool verifyData(String msg, String check)
{
byte[] msgByte = System.Convert.FromBase64String(msg);
byte[] checkByte = System.Convert.FromBase64String(check);
X509Certificate2 pub = new X509Certificate2(cerpath);
RSACryptoServiceProvider rsaPublic = pub.PublicKey.Key as RSACryptoServiceProvider;
return rsaPublic.VerifyData(msgByte, "MD5", checkByte);
}


此方式等同于JAVA mad5withrsa
