最好的加密就是通過你的網(wǎng)站去加密！用網(wǎng)絡(luò)服務(wù)器驗證把一些主要程序都可以加載到服務(wù)器上！這樣你的程序加密就完美了！ （個人觀點純屬不懂裝懂的。哈哈見笑）
專注于為中小企業(yè)提供做網(wǎng)站、網(wǎng)站建設(shè)服務(wù),電腦端+手機端+微信端的三站合一,更高效的管理,為中小企業(yè)市中免費做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動了數(shù)千家企業(yè)的穩(wěn)健成長，幫助中小企業(yè)通過網(wǎng)站建設(shè)實現(xiàn)規(guī)模擴充和轉(zhuǎn)變。
我覺得你的并不是RSA加密解密算法。
在.net的有一個System.Security.Cryptography的命名空間，里面有一RSACryptoServiceProvider的類用來對byte進行RSA加密解密。
具體例子如下：
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),
//and a boolean flag specifying no OAEP padding.
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)
{
try
{
//Create a new instance of RSACryptoServiceProvider.
RSACryptoServiceProvider RSA = new 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);
}
//Catch and display a CryptographicException
//to the console.
catch(CryptographicException e)
{
Console.WriteLine(e.Message);
return null;
}
}
static public byte[] RSADecrypt(byte[] DataToDecrypt, RSAParameters RSAKeyInfo,bool DoOAEPPadding)
{
try
{
//Create a new instance of RSACryptoServiceProvider.
RSACryptoServiceProvider RSA = new RSACryptoServiceProvider();
//Import the RSA Key information. This needs
//to include the private key information.
RSA.ImportParameters(RSAKeyInfo);
//Decrypt the passed byte array and specify OAEP padding.
//OAEP padding is only available on Microsoft Windows XP or
//later.
return RSA.Decrypt(DataToDecrypt, DoOAEPPadding);
}
//Catch and display a CryptographicException
//to the console.
catch(CryptographicException e)
{
Console.WriteLine(e.ToString());
return null;
}
}
}
[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#]
try
{
//Create a new RSACryptoServiceProvider object.
RSACryptoServiceProvider RSA = 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.
RSAParameters RSAParams = RSA.ExportParameters(false);
}
catch(CryptographicException e)
{
//Catch this exception in case the encryption did
//not succeed.
Console.WriteLine(e.Message);
}
網(wǎng)上有很多專業(yè)的加密教程
最適合小開發(fā)者的軟件加密方式就是下面這個
獲取硬件信息和個人注冊時的姓名手機號等一系列信息，通過預(yù)先設(shè)定好的加密函數(shù)進行散列加密，生成一個只有本人本機能使用的序列號，軟件正版授權(quán)的時候用同樣的方式生成序列號進行比對，一樣則通過
