我正在阅读一本名为从 wrox 开始 asp.net 安全性的书，我在这一部分中，它显示了使用 rijndael 的代码片段，该示例未包含在可下载的源代码中。我决定在论坛中寻求（专业）帮助。
如果您也尝试测试它，并希望给出一个关于我如何实现它的示例（代码），那就太棒了。
这是代码：
public class EncryptionRijndael
{
public EncryptionRijndael()
{
//
// TODO: Add constructor logic here
//
}
public static byte[] GenerateRandomBytes(int length)
{
byte[] key = new byte[length];
RNGCryptoServiceProvider provider = new RNGCryptoServiceProvider();
provider.GetBytes(key);
return key;
}
public void GetKeyAndIVFromPasswordAndSalt(string password, byte[] salt,SymmetricAlgorithm symmetricAlgorithm,ref byte[] key, ref byte[] iv)
{
Rfc2898DeriveBytes rfc2898DeriveBytes =
new Rfc2898DeriveBytes(password, salt);
key =
rfc2898DeriveBytes.GetBytes(symmetricAlgorithm.KeySize / 8);
iv =
rfc2898DeriveBytes.GetBytes(symmetricAlgorithm.BlockSize / 8);
}
public static byte[] Encrypt(byte[] clearText, byte[] key, byte[] iv)
{
// Create an instance of our encyrption algorithm.
RijndaelManaged rijndael = new RijndaelManaged();
// Create an encryptor using our key and IV
ICryptoTransform transform = rijndael.CreateEncryptor(key, iv);
// Create the streams for input and output
MemoryStream outputStream = new MemoryStream();
CryptoStream inputStream = new CryptoStream(
outputStream,
transform,
CryptoStreamMode.Write);
// Feed our data into the crypto stream.
inputStream.Write(clearText, 0, clearText.Length);
// Flush the crypto stream.
inputStream.FlushFinalBlock();
// And finally return our encrypted data.
return outputStream.ToArray();
}
static byte[] Decrypt(byte[] cipherText, byte[] key, byte[] iv)
{
// Create an instance of our encyrption algorithm.
RijndaelManaged rijndael = new RijndaelManaged();
// Create an decryptor using our key and IV ;
ICryptoTransform transform = rijndael.CreateDecryptor(key, iv);
// Create the streams for input and output
MemoryStream outputStream = new MemoryStream();
CryptoStream inputStream = new CryptoStream(outputStream,transform,CryptoStreamMode.Write);
// Feed our data into the crypto stream.
inputStream.Write(cipherText, 0, cipher.Length);
// Flush the crypto stream.
inputStream.FlushFinalBlock();
// And finally return our decrypted data.
return outputStream.ToArray();
}
}
先生/女士，您的回答会很有帮助。谢谢++（如果你能告诉我如何正确调用加密和解密，那就太棒了）
