Rijndael 加密算法在 .NET 中使用以下示例中的 3 个流实现:Rinjdael。
有人可以向我解释这些流在做什么吗?如何/为什么使用它们?
// Declare the streams used
// to encrypt to an in memory
// array of bytes.
MemoryStream msEncrypt = null;
CryptoStream csEncrypt = null;
StreamWriter swEncrypt = null;
// Declare the RijndaelManaged object
// used to encrypt the data.
RijndaelManaged aesAlg = null;
try
{
// Create a RijndaelManaged object
// with the specified key and IV.
aesAlg = new RijndaelManaged();
aesAlg.Key = Key;
aesAlg.IV = IV;
// Create a encryptor to perform the stream transform.
ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV);
// Create the streams used for encryption.
msEncrypt = new MemoryStream();
csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write);
swEncrypt = new StreamWriter(csEncrypt);
//Write all data to the stream.
swEncrypt.Write(plainText);
}
