We should look at using an optimised version of NTRUPrime, at the moment we're just using a generic version that isn't very fast. There's probably a 3-5x saving to be made... -d

...Penalties that is applied when a connection is dropped by the new RefuseConnection keyword. * sshd(8): add a "Match invalid-user" predicate to sshd_config Match options that matches when the target username is not valid on the server. * ssh(1), sshd(8): update the Streamlined NTRUPrime code to a substantially faster implementation. * ssh(1), sshd(8): the hybrid Streamlined NTRUPrime/X25519 key exchange algorithm now has an IANA-assigned name in addition to the "@openssh.com" vendor extension name. This algorithm is now also available under this name &quot...
