RE: [Jsdsi-users] KeyPair

[Luis P. <lp...@ne...>]

Marek,

It help if u send the exact error. But try this:
	- If the error is "SPKI not found", then u have to load jsdsi
provider, i.e, jsdsi.Provider.install() and cryptix provider.

But, if your problem is a ClassCastException then u have an error on =
your
code and u should change this(following your code):

	java.security.KeyPair gk =3D jsdsi.util.KeyPairFactory.create("RSA",
2048);
	java.io.FileOutputStream fos =3D new
java.io.FileOutputStream("gde/tests/test.pub");
	java.io.ObjectOutputStream oos =3D new
java.io.ObjectOutputStream(fos);
// I have changed things here, tooked "toString()"=09
	oos.writeObject(gk);
// Doesn't make sense writing an object like gk.toString()!!
// writeObject serializes the object. U can't cast from "String" to
"KeyPair"=20
	oos.close();

	java.security.KeyPair gk;
	java.io.FileInputStream fos =3D new
java.io.FileInputStream("gde/tests/test.pub");
	java.io.ObjectInputStream oos =3D new java.io.ObjectInputStream(fos);
    	gk =3D (java.security.KeyPair)oos.readObject();
	oos.close();
=09

=BB    =20
=BB     How can't I load this object and retype in a KeyPair?=20
=BB     This code don't
