I regularly use C-Kermit to do this kind of thing, but using telnetd-ssl
on the target machine rather than sshd.

Have a look at:

http://www.columbia.edu/kermit/ck90.html

To get a full range of features I download the source from the above
site and do a:

make linux+openssl+zlib+shadow+pam

followed by

checkinstall make install

on Debian. (You need packages for checkinstall openssl, openssl-dev,
zlib, but it builds easily)

An example of logging in to the remote machine, obtaining and building
C-Kermit on that machine, then using C-Kermit to download the source
tarball on that machine follows:

C-Kermit>telnet 192.168.1.101
  Trying 192.168.1.101... (OK)
  Negotiations........Authenticating with SSL

[TLS - AES256-SHA              SSLv3 Kx=RSA      Au=RSA  Enc=AES(256)
Mac=SHA1
Compression: zlib compression
  (OK)

Goodbye.
amarsh04@remote:~/kermit-src$ gzip -dc x26.tar.gz|tar -xvf /dev/fd/0

then edited the makefile to change prefix to /usr and manroot to
$(prefix)/share

then ran:

make linux+openssl+zlib+shadow+pam
checkinstall make install

To move the x.26.tar.gz file to the local machine I ran:

amarsh04@remote:~/kermit-src$ kermit -s x26.tar.gz
Return to your local Kermit and give a RECEIVE command.

KERMIT READY TO SEND...
  SENT: [/home/amarsh04/kermit-src/x26.tar.gz] To:
[/home/amarsh04/kermit-src/x26.tar.gz] (OK)

C-Kermit does telnet client including with ssl and other
encryption/authentication options, SSH client using an external ssh
program, ftp client, and kermit client and server.

C-Kermit is worth a look at and an investment in some time learning how
to use it.
