These functions work like
  <a class="Xr" title="Xr" href="crypto_from_eddsa_private.html">crypto_from_eddsa_private(3monocypher)</a>
  and
  <a class="Xr" title="Xr" href="crypto_from_eddsa_public.html">crypto_from_eddsa_public(3monocypher)</a>,
  except that they operate on Ed25519 key pairs rather than key pairs for EdDSA
  with BLAKE2b. Please see the documentation for those functions for details.

<b class="Fn" title="Fn">crypto_from_ed25519_public</b>() is actually
