示例1: Main
static int Main ()
{
string filename = Path.Combine (AppDomain.CurrentDomain.BaseDirectory,
"encrypt.tmp");
string data = "this is sensitive data";
DESCryptoServiceProvider des = new DESCryptoServiceProvider ();
des.GenerateIV ();
des.GenerateKey ();
// ----------- WRITING ENCRYPTED SERIALIZED DATA ------------------
Stream stream = new FileStream (filename, FileMode.Create, FileAccess.Write);
stream = new CryptoStream (stream, des.CreateEncryptor (), CryptoStreamMode.Write);
BinaryFormatter bformatter = new BinaryFormatter ();
bformatter.Serialize (stream, data);
stream.Close ();
stream = null;
bformatter = null;
data = string.Empty;
// ----------- READING ENCRYPTED SERIALIZED DATA ------------------
stream = new FileStream (filename, FileMode.Open, FileAccess.Read);
stream = new CryptoStream (stream, des.CreateDecryptor (), CryptoStreamMode.Read);
bformatter = new BinaryFormatter ();
data = (string) bformatter.Deserialize (stream);
stream.Close ();
//----------- CHECK RESULTS ----------------
if (data != "this is sensitive data")
return 1;
return 0;
