Right.  It doesn't help if everyone uses custom curves but most won't be
able to encrypt messages to that key.  There is also the question of
parameter validation.

I guess we will add a few more curves if there is a real demand for it,
but this should be limited to what is really needed.  Frankly, I was one
of those who favored an OID approach instead of just a simple number to
describe the curve.  This is the OpenPGP feature which allows us to
extend ECC.  It is more like all the algorithm ids we have, we need to
limit them and add a new algorithm only for a real (political) reason,
like Camellia.



Die Gedanken sind frei.  Ausnahmen regelt ein Bundesgesetz.
