有没有一种简单的方法来加密java对象？

我想将序列化对象存储到文件中，但我想对其进行加密。它不需要非常强的加密。我只是想要一些简单的东西（最好是最多几行代码），这会让其他人加载起来更加困难。我已经研究过 SealedObject 但关键是阻止我。理想情况下，我只想传递一个字符串作为加密/解密对象的密钥。

有什么建议么？

试试这个代码：

String fileName = "result.dat"; //some result file

//You may use any combination, but you should use the same for writing and reading
SecretKey key64 = new SecretKeySpec( new byte[] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07 }, "Blowfish" );
Cipher cipher = Cipher.getInstance( "Blowfish" );

//Code to write your object to file
cipher.init( Cipher.ENCRYPT_MODE, key64 );
Person person = new Person(); //some object to serialise
SealedObject sealedObject = new SealedObject( person, cipher);
CipherOutputStream cipherOutputStream = new CipherOutputStream( new BufferedOutputStream( new FileOutputStream( fileName ) ), cipher );
ObjectOutputStream outputStream = new ObjectOutputStream( cipherOutputStream );
outputStream.writeObject( sealedObject );
outputStream.close();

//Code to read your object from file
cipher.init( Cipher.DECRYPT_MODE, key64 );
CipherInputStream cipherInputStream = new CipherInputStream( new BufferedInputStream( new FileInputStream( fileName ) ), cipher );
ObjectInputStream inputStream = new ObjectInputStream( cipherInputStream );
SealedObject sealedObject = (SealedObject) inputStream.readObject();
Person person1 = (Person) sealedObject.getObject( cipher );
