我觉得你的并不是RSA加密解密算法.
在.net的有一个System.Security.Cryptography的命名空间,里面有一RSACryptoServiceProvider的类用来对byte进行RSA加密解密.
具体例子如下：
using System;
using System.Security.Cryptography;
using System.Text;
class RSACSPSample
{
static void Main()
try
//Create a UnicodeEncoder to convert between byte array and string.
UnicodeEncoding ByteConverter = new UnicodeEncoding();
//Create byte arrays to hold original, encrypted, and decrypted data.
byte[] dataToEncrypt = ByteConverter.GetBytes("Data to Encrypt");
byte[] encryptedData;
byte[] decryptedData;
//Create a new instance of RSACryptoServiceProvider to generate
//public and private key data.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Pass the data to ENCRYPT, the public key information
//(using RSACryptoServiceProvider.ExportParameters(false),
//and a boolean flag specifying no OAEP padding.
encryptedData = RSAEncrypt(dataToEncrypt,RSA.ExportParameters(false), false);
//Pass the data to DECRYPT, the private key information
//(using RSACryptoServiceProvider.ExportParameters(true),
decryptedData = RSADecrypt(encryptedData,RSA.ExportParameters(true), false);
//Display the decrypted plaintext to the console.
Console.WriteLine("Decrypted plaintext: {0}", ByteConverter.GetString(decryptedData));
}
catch(ArgumentNullException)
//Catch this exception in case the encryption did
//not succeed.
Console.WriteLine("Encryption failed.");
static public byte[] RSAEncrypt(byte[] DataToEncrypt, RSAParameters RSAKeyInfo, bool DoOAEPPadding)
//Create a new instance of RSACryptoServiceProvider.
//Import the RSA Key information. This only needs
//toinclude the public key information.
RSA.ImportParameters(RSAKeyInfo);
//Encrypt the passed byte array and specify OAEP padding.
//OAEP padding is only available on Microsoft Windows XP or
//later.
return RSA.Encrypt(DataToEncrypt, DoOAEPPadding);
//to the console.
catch(CryptographicException e)
Console.WriteLine(e.Message);
return null;
static public byte[] RSADecrypt(byte[] DataToDecrypt, RSAParameters RSAKeyInfo,bool DoOAEPPadding)
//Import the RSA Key information. This needs
//to include the private key information.
//Decrypt the passed byte array and specify OAEP padding.
return RSA.Decrypt(DataToDecrypt, DoOAEPPadding);
Console.WriteLine(e.ToString());
[Visual Basic]
Try
'Create a new RSACryptoServiceProvider object.
Dim RSA As New RSACryptoServiceProvider()
'Export the key information to an RSAParameters object.
'Pass false to export the public key information or pass
'true to export public and private key information.
Dim RSAParams As RSAParameters = RSA.ExportParameters(False)
Catch e As CryptographicException
'Catch this exception in case the encryption did
'not succeed.
Console.WriteLine(e.Message)
End Try
[C#]
//Create a new RSACryptoServiceProvider object.
//Export the key information to an RSAParameters object.
//Pass false to export the public key information or pass
//true to export public and private key information.
RSAParameters RSAParams = RSA.ExportParameters(false);
在FormLoad事件里,写如下代码：
If MsgBox("是否打开程序?", MsgBoxStyle.OkCancel) = MsgBoxResult.Cancel Then
End
End If
大概方法是这样,要想加密码的话,将MsgBox()换成你自己写的对话框.
如果还嫌不够具体的话,你这点儿分就不够...
网上有很多专业的加密教程
最适合小开发者的软件加密方式就是下面这个
获取硬件信息和个人注册时的姓名手机号等一系列信息,通过预先设定好的加密函数进行散列加密,生成一个只有本人本机能使用的序列号,软件正版授权的时候用同样的方式生成序列号进行比对,一样则通过
