None of Ed25519, Ed25519ph, Ed448, Ed448ph, X25519 and X448 is a curve,
those all are diffie-hellman algorithms or signature algorithms.

Those algorithms are the pracical applications of the CFRG ECC work
to JOSE (the direct curves don't have much use[1])


[1] I do know only one spec (HTTP auth type) that could use the raw
curves themselves.
