[tahoe-dev] Down with ECDSA

Note that specific hand-picked curves can be much faster than random curves
(like the Brainpool ones). Crypto++'s general elliptic curve code isn't
terribly efficient, which makes this worse.
According to Tanja Lange's earlier post, NACL will have digitial signatures,
presumably on a fast curve, and I plan to implement it too in Crypto++ after
they release the code or specification. So if speed is a big concern, you
might want to either wait for that, or plan an upgrade path. It should be
around 5-10 times faster than the current ECDSA implementation in Crypto++
with Brainpool curve.
