type Private ecdsa.PrivateKey? I mean, this struct wrapper seems to be useless now.

In this case method (*keys.PrivateKey).PublicKey() duplicates field (ecdsa.PrivateKey).PublicKey. At the same time we cannot remove the method as we need to have access to keys.PublicKey via keys.PrivateKey (not to ecdsa.PublicKey). So we can either rename (*keys.PrivateKey).PublicKey() or let PrivateKey remain a struct. What do you prefer?

OK, let it be a struct for now, we can refactor it later.

type Public ecdsa.PublicKey
Now we have not only Random EC curve, but also Koblitz curve, so it will be useful to have information about the curve for each particular EC point. ecdsa.PublicKey has this information.
