示例1: Main
//引入命名空间
using System;
using System.Security.Cryptography;
public class DataProtectionSample
{
// Create byte array for additional entropy when using Protect method.
static byte [] s_aditionalEntropy = { 9, 8, 7, 6, 5 };
public static void Main()
{
// Create a simple byte array containing data to be encrypted.
byte [] secret = { 0, 1, 2, 3, 4, 1, 2, 3, 4 };
//Encrypt the data.
byte [] encryptedSecret = Protect( secret );
Console.WriteLine("The encrypted byte array is:");
PrintValues(encryptedSecret);
// Decrypt the data and store in a byte array.
byte [] originalData = Unprotect( encryptedSecret );
Console.WriteLine("{0}The original data is:", Environment.NewLine);
PrintValues(originalData);
}
public static byte [] Protect( byte [] data )
{
try
{
// Encrypt the data using DataProtectionScope.CurrentUser. The result can be decrypted
// only by the same current user.
return ProtectedData.Protect( data, s_aditionalEntropy, DataProtectionScope.CurrentUser );
}
catch (CryptographicException e)
