Matt Sicker commented on SSHD-704:
----------------------------------
I just noticed that there's [JEP 339|https://openjdk.java.net/jeps/339]
proposed for Java 15 which will finally add standard support for
EdDSA/Ed25519/Ed448 which will likely be the fastest way to use it in Java once
available. Similar to how [JEP 324|https://openjdk.java.net/jeps/324] added
X25519/X448 support. Amusingly enough, it sounds like the internal
implementation of OpenJDK's ECDH support uses EdDSA representations for the
math anyways.
I'm going to do some further digging around these algorithms as it's a similar
dependency knot in SSHD-1017.
