File.Encrypt
是一项操作系统功能,但听起来您确实想控制加密的完成方式。

// This is where the data will be written do.
MemoryStream dataStream = new MemoryStream();
// The encryption vectors
byte[] key = {145,12,32,245,98,132,98,214,6,77,131,44,221,3,9,50};
byte[] iv = {15,122,132,5,93,198,44,31,9,39,241,49,250,188,80,7};
// Build the encryption mathematician
using (TripleDESCryptoServiceProvider encryption = new TripleDESCryptoServiceProvider())
using (ICryptoTransform transform = encryption.CreateEncryptor(key, iv))
using (Stream encryptedOutputStream = new CryptoStream(dataStream, transform, CryptoStreamMode.Write))
using (StreamWriter writer = new StreamWriter(encryptedOutputStream))
{
// In this block, you do your writing, and it will automatically be encrypted
writer.Write("This is the encrypted output data I want to write");
}
加密不适合胆小的人。但请预先警告,在尝试此操作之前,您确实应该对常规 IO 和数据流有强烈的了解。
