[Proftpd-user] Does proftpd ed25519 ssh key authentication ?

Hello,

I've compiled proftpd version 1.3.6 on debian with openssl 1.0.2l and
libsodium 1.0.11.

I generated a ssh key pair with the command "ssh-keygen -t ed2551", converted the key to rfc4716 format and
copied it to the users authorized_key file. 

When I try to login to sftp I get:

"unsupported public key algorithm 'ssh-ed25519' requested, rejecting request"  in the sftp logfile.

Does proftpd support ed25519 key for user authentication ?

I configure proftpd as follows:

./configure \
  --prefix=/usr \
  --sbindir=/usr/sbin \
  --sysconfdir=/etc \
  --localstatedir=/var/lib/proftpd \
  --mandir=/usr/share/man \
  --disable-sendfile \
  --disable-devel \
  --disable-auth-pam \
  --disable-ident \
  --disable-ncurses \
  --enable-timeout-idle=3600 \
  --enable-timeout-no-transfer=3600 \
  --enable-openssl \
  --with-modules=mod_sftp:mod_readme:mod_rewrite:mod_exec

I also tried it with openssl1.1, but no luck.
I also tried proftpd from git master (98baae721738e199dd3a1957a78ef54b3cb3ee9a), but it doesn't work either.

With RSA key a login to the server succeeded.
