NET中执行这个操作的中介者也是一个流类型，叫做CryptoStream。 4.4 CryptoStream的构造函数如下，共有三个参数： public CryptoStream(Stream stream, ICryptoTransform transform, CryptoStreamMode 可见，CryptoStream总是接受密文流，并且根据CryptoStreamMode枚举的值来决定是将明文流写入到密文流（加密），还是将密文流读入到明文流中（解密）。 using (CryptoStream cryptoStream = new CryptoStream(encryptedStream, encryptor, CryptoStreamMode.Write using (CryptoStream cryptoStream = new CryptoStream(encryptedStream, decryptor, CryptoStreamMode.Read

.NET中的密码学–对称加密
你可以直接使用它的实例，但是在大多数情况下，为了方便，我们通过其他的名叫CryptoStream来完成。让我们看一个例子是如何使用它的。 CryptoStream 类 CryptoStream类通常被使用来读写数据同时也在读或者写的时候加密或者解密数据。它是简单的包装了一下原始流类Stream。 mStream = new CryptoStream(fileStream,mTransform,CryptoStramMode.Read) fileStream是请求从硬盘或者内存中读取数据的原始文件的流 ICryptTramsform mTransform = mCryptProv.CreateEncryptor(); CryptoStream mCSWriter = new CryptoStream( // 将内存点置0 mMemStr.Position = 0; mTransform = mCryptProv.CreateDecryptor(); CryptoStream mCSReader = new
