Comment 6 for bug 907675

http://twistedmatrix.com/trac/ticket/8798 is progress towards both keys, and looks like ECDSA got support with http://twistedmatrix.com/trac/ticket/8828, now just Ed25519 is in https://twistedmatrix.com/trac/ticket/8966 (Though, http://twistedmatrix.com/trac/ticket/8854 might hold things up a tad.)

Still, there's progress and that's good.
