在C#中实现.resx资源的加密和解密可以通过以下步骤:
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());
}
}
}
}
使用以上代码示例,可以实现对.resx资源文件的加密和解密操作。请注意在实际应用中,需要根据具体的需求和安全要求选择合适的加密算法和密钥管理方式。
