Encrypting Objects

Is it at all possible to perform encryption on an object? Using bouncycastle to do RSA assymetric encryption. I have only seen examples of encrypting byte arrays and files.

I have an object of type Student. That basically contains a couple of strings containing valuable data. I would like to encrypt the Student object that encapsulates this data. Is this possible? Or will i be forced to encrypt the contents of this object individually?

Any sample code will also be very helpful

Thanking you in advance

If you're object implements the Serializable interface then you can write it out to a byte[] using writeObject() and then encrypt that array.

okay but then how would I send that byte array in encrypted form to a servlet, bcos its no longer an objectOutputStream

If you need the encrypted byte[] to be sent over as an Object, any array in Java is an object so you shouldn't have a problem there. The servlet will need access to a key to decrypt the array however.

yeah thats okay. The servlet will have access to either a keystore or a database that conatins the necessary private key.

But i have found another problem. I am using the bouncycastle implementation, but will this work with an applet in a browser. I have only found examples of assyemtric encryption in applications

Thanks once again

I have not been involved with Applets recently at any rate. So maybe someone else will know. I would suspect signing would be necessary. Good luck!

Use Sealed Objects
