c# - 是否有将 AES 256 加密实现为流的 .NET 加密库？

Question

我希望能够在数据流式传输到磁盘或从磁盘流式传输时加密/解密数据。我知道我可以编写自己的 Stream 并在那里实现加密，但我不想冒险做错。有没有以类似于以下代码的方式工作的库？

byte[] encryptionKey = ;
byte[] initVector = ;

var fileStream = new FileStream(filePath, FileMode.CreateNew, FileAccess.Write);
var encryptionStream = new AesEncryptionStream(fileStream, initVector, encryptionKey);
var gzStream = new GZipStream(encryptionStream, CompressionMode.Compress);
var writer = new BinaryWriter(gzStream);

您正在寻找 RijndaelManaged 和 CryptoStream 类:

var aes = new RijndaelManaged { Key = ..., IV = ... };

using (var encryptor = aes.CreateEncryptor()) 
using (var cryptoStream = new CryptoStream(gzStream, encryptor, CryptoStreamMode.Write))
using (var writer = new BinaryWriter(cryptoStream)) {
    ...
}
