Writing and retrieving RSA keys from a file

Hello all,

I'm trying to write a generated RSAPublicKey and RSAPrivateKey to a file, and then, later retrieve them.

I thought I could use ObjectInput/OutputStream to do that, but when I do so I get the exception java.io.NotSerializableException: java.io.ObjectOutputStream

(I'm surprised, because RSAPublic/PrivateKey are serializable, aren't they ?).

If this is not the way to do it, I do not know how (no key constructor reading from byte [] ...).

Can somebody please help me ?

Thanks,

Axelle.
