It isn't really broken, but the recommended key sizes have grown significantly. I mean, the factor to divide RSA/DH/ElGamal key sizes by to get equivalent security in ECC has shrunk. At least, I've heard so, I don't remember what keys sizes were advertised in the beginnings of ECC. -- Lionel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
