  TripleDESCryptoServiceProvider tripleDES = new TripleDESCryptoServiceProvider();
           
  ICryptoTransform cTransform = tripleDES.CreateEncryptor();
  byte[] resultArray = cTransform.TransformFinalBlock(inputArray, 0, inputArray.Length);
  tripleDES.Clear();

}

推荐答案

您只加密文件名 FileUpload1.SaveAs（uploadedFilePath + Encrypt（FileUpload1） .FileName））; 。要加密整个文件，您需要加密文件内容（不仅是名称）。



Nathan Blomquist写了一篇关于此的文章：

使用C＃中的散列验证进行文件加密/解密 [ ^ ]

You are encrypting the filename only FileUpload1.SaveAs(uploadedFilePath + Encrypt(FileUpload1.FileName));. To encrypt the whole file you need to encrypt the file content (not only the name).
