Encrypt large SealedObject

Hello,

I'm trying to create a SealedObject that contains a Serializable object and a cipher that initialise with RSA. I want to create a pair of keys for each user, so that's why I'm using RSA. I'm getting an Exception when trying to encrypt this object and I know that the reason is because key's size. My question is how I can create a SealedObject that will contains an Object[] (with two integers and a SecretKey) and encrypt it using user's public key?

Thanks in advance,

Too difficult a question for “beginning”. Moving to security forum.

Can you post the code that you've tried. I'd like to see how you create the cipher you use for encrypting the sealedObject
 
I agree. Here's the link: http://aspose.com/file-tools
