I'm not quite sure of the actual scaling capabilities, but I know you can create fairly large keys (10240-20480 bits) for use with many VPN's. FreeS/WAN, in particular, in shared-key mode will use these large keys, both public and private, for the initial authentication and initialization of a tunnel. > I've always wanted to jack the key sizes under my control (ssh + pgp) > to, oh say, 10,000 bits if I could.

The algorithms themselves are perfectly capable of large keys. However, the application may be limited as to the size that it will accept. Then again, if you have the source, I suppose you can change that, too ;-) C-Ya, Kenny -- ---------------------------------------------------------------------------- "Tact is just *not* saying true stuff" -- Cordelia Chase Kenneth E.
