Features:

Tinyssh doesn't have...scp, sftp
...using NaCL/TweetNaCL
I lost interest there.
scp and sftp are *the* main use I have for ssh. I have three computers
of my own (desktop and two laptops, all Linux), there's another one
(Windows) the family uses, and I find that the best way to copy something
from a to b is to use scp or something like FileZilla.
And no, I'm not interested in adding another daemon, transferring
files in plain mode, or having to run commands on both ends.
As far as the second feature I quote goes, see:
landley.net/notes.html#31-03-2014
dropbear is a permissively licensed mcb that gets a good workout. Seems
like it fits with toybox.
And libtomcrypt seems like the better place to start, should an ssh
server and client be desired.
I note also that there's yet another small ssh server, moussh:
ftp.rodents-montreal.org/mouse/local/src/moussh
The developer was at one point considering using some of the libtom*
libraries; it currently needs gmp and a set of homegrown crypto libs.
It does have one or two rather frightening notes: it requires a
special preprocessor (included) or a version of gcc patched to support
"labeled control structure", whatever that is.
While we're talking about crypto, I might as well mention axtls.
It's a small BSD-licensed TLS1 library that uses kconfig with perhaps
too many options (what *FLAGS you want, which keys/certificates, openssl
API, ...).
Thanks,
Isaac Dunham
