Answer 1

您应该使用CryptoStream,它将自动调用正确的ICryptoTransform方法.

例如:

var stream = new MemoryStream();
using (var transform = symAlgo.CreateEncryptor())
using (var cryptoStream = new CryptoStream(stream, transform, CryptoStreamMode.Write))
using (var writer = new StreamWriter(cryptoStream))
    writer.Write(someString);

byte[] cipherBytes = stream.ToArray();
