我找到了一種方法去加密和連載/連載對象申請暫停期間/加密/序列化之後
C# Encrypt serialized file before writing to disk
這裏是我的代碼...
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.Serialization.Formatters.Binary;
using System.Security.Cryptography;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Digital_Only_Calculator
{
class EncryptionSerialiser
{
byte[] key = { 1, 2, 3, 4, 5, 6, 7, 8 }; // Where to store these keys is the tricky part,
// you may need to obfuscate them or get the user to input a password each time
byte[] iv = { 1, 2, 3, 4, 5, 6, 7, 8 };
string path = Application.StartupPath + @"\" + "test.ser";
DESCryptoServiceProvider des = new DESCryptoServiceProvider();
public void EncryptThenSerialise(object obj)
{
// Encryption
using (var fs = new FileStream(path, FileMode.Create, FileAccess.Write))
using (var cryptoStream = new CryptoStream(fs, des.CreateEncryptor(key, iv), CryptoStreamMode.Write))
{
BinaryFormatter formatter = new BinaryFormatter();
// This is where you serialize the class
formatter.Serialize(cryptoStream, obj);
}
}
public Person DecryptThenSerialise(object obj)
{
// Decryption
using (var fs = new FileStream(path, FileMode.Open, FileAccess.Read))
using (var cryptoStream = new CryptoStream(fs, des.CreateDecryptor(key, iv), CryptoStreamMode.Read))
{
BinaryFormatter formatter = new BinaryFormatter();
// This is where you deserialize the class
Person deserialized = (Person)formatter.Deserialize(cryptoStream);
return deserialized;
}
}
}
}
,對於編碼測試...
Person p = new Person();
p.Name = "Bill";
p.Age = 40;
EncryptionSerialiser ESER = new EncryptionSerialiser();
ESER.EncryptThenSerialise(p);
Person p2 = new Person();
p2 = ESER.DecryptThenSerialise(p2);
問題是,應用程序不能繼續在這行之後(你可以在上面的EncryptThenSerialise方法中看到。
formatter.Serialize(cryptoStream, obj);
Person類...
public class Person
{
public String Name { get; set; }
public int Age { get; set; }
}
但它確實似乎加密和序列化對象,作爲一個新的文件被創建,當打開長相加密。它只是不會繼續執行序列化。
任何想法的人?
「應用程序不會在這行後繼續」它掛起,還是崩潰? –
它似乎是「突破」,即退出該方法,並允許用戶使用控制表單等。所以它幾乎就像它認爲它已完成,但它沒有。 – user3755946
