We have no idea. The methods used to factor number continue to slowly get better, and it has been quite a while since there was a single large improvement. That could mean that there are no more improvements to be made, or that some smart cryptographer who isn't focused on the SHA-3 competition is about to make another big improvement, or something in between. --Paul Hoffman, Director --VPN Consortium --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
