在C#中實現.resx資源的加密和解密可以通過以下步驟:
using System;
using System.IO;
using System.Resources;
using System.Security.Cryptography;
using System.Text;
public class ResourceEncryptor
{
public static void EncryptResourceFile(string inputFile, string outputFile, string key)
{
byte[] keyBytes = Encoding.ASCII.GetBytes(key);
byte[] inputFileBytes = File.ReadAllBytes(inputFile);
using (Aes aesAlg = Aes.Create())
{
aesAlg.Key = keyBytes;
aesAlg.IV = Encoding.ASCII.GetBytes("1234567890123456");
ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);
using (MemoryStream msEncrypt = new MemoryStream())
{
using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write))
{
csEncrypt.Write(inputFileBytes, 0, inputFileBytes.Length);
}
File.WriteAllBytes(outputFile, msEncrypt.ToArray());
}
}
}
}
public class ResourceDecryptor
{
public static void DecryptResourceFile(string inputFile, string outputFile, string key)
{
byte[] keyBytes = Encoding.ASCII.GetBytes(key);
byte[] inputFileBytes = File.ReadAllBytes(inputFile);
using (Aes aesAlg = Aes.Create())
{
aesAlg.Key = keyBytes;
aesAlg.IV = Encoding.ASCII.GetBytes("1234567890123456");
ICryptoTransform decryptor = aesAlg.CreateDecryptor(aesAlg.Key, aesAlg.IV);
using (MemoryStream msDecrypt = new MemoryStream())
{
using (CryptoStream csDecrypt = new CryptoStream(msDecrypt, decryptor, CryptoStreamMode.Write))
{
csDecrypt.Write(inputFileBytes, 0, inputFileBytes.Length);
}
File.WriteAllBytes(outputFile, msDecrypt.ToArray());
}
}
}
}
使用以上代碼示例,可以實現對.resx資源文件的加密和解密操作。請注意在實際應用中,需要根據具體的需求和安全要求選擇合適的加密算法和密鑰管理方式。
