Comment(by davidsarah):
I'm confused. Shortening the read caps does not depend on ECDSA. The semi-
private key approach depends on ECDSA (to get ~2K bit read caps), but that
approach doesn't give the shortest read caps. The mutable read caps in the
Elk Point designs would be about K+50 bits, i.e. nearly a 1/3rd shorter,
regardless of public key algorithm, and without depending on semi-private
keys. (The immutable read caps are also 1/3rd shorter -- 2K instead of
3K.)
[This is the size of the cryptovalues; there is obviously some fixed
overhead in the URL encoding.]
