Add support for ED25519 #1

https://github.com/david-oswald/jc_curve25519 converts Curve25519 into Weierstrass form and then uses the standard KeyAgreement

any news on this feature?

Dear @sdellava , no update yet - still planned, but lacking time to implement it

Is it possible to use the native Curves of Javacard 3.1 with JCMathLib? My Application needs ED25519 KeyDerivation and some other Math operations. If it works without modification I will just use version 3.1, if not I might drop to version 3.0.5 and use this: https://github.com/dufkan/JCEd25519 .

@jonycoo to use native curves from JC API spec 3.1, you need to have smartcard supporting this version - we do not have such card yet so we cannot test such usage. Anyway, @dufkan is involved in JCMathLib development and https://github.com/dufkan/JCEd25519 is good way to go (if you have smartcard supporting 3.0.5)
