Thanks for the info. But then which algorithm from the SunJCE provider
would save me from getting NoSuchAlgorithmException ?
I have tried DSA and DES ? If I do not use KeyPairGenerator and simply
use KeyGenerator then DES work OK.

But with KeyPairGenerator it does not. I am sure I am missing something.
But not able to figure it out.

Narendra
