Indeed. Didn't see that in the original Swiss version. Oh well, use
ECDSA.
As an aside, didn't Schneier mention some 200 different signature schemes
using mod-exp in the second version of AC? I would think that most of
those translate to ECC directly. The loss of NR is minor bummer, there
are more than enough other algorithms to make up for it.
Thanks Paulo. Anybody know of anything else?
Patience, persistence, truth,
