You can try to get/make a version of CFT that works with old SSH libs. Sometimes it is easy, if no function prototypes change and the list of object names linked is still supported.
You can ask your software provider to do a maintenance release and get their ssh up to date (seems insecure not to!). Be careful they do not go farther, if there is a farther.
You can write a pair of apps to fake the library, where one seems to be the desired, mising library but is a C++ wrapper and the other links to the ssh lib you have. When the fake libssh.x gets a call, it sends it to the second piece linked to libssh.x-1, which makes the call, and sends the response back so the first can return it. If the first changes directory, it needs to detect that so the other can follow, else file names in arguments will not work. If there is any other activity that is very local, like passing open fd, that would be a problem. Data could be in an mmap'd file space so pointers can be passed, but pointers in to any call mean the object pointed to needs copying back and forth. If you are lucky, you only need a few calls to make it happy.

4. UNIX for Dummies Questions & Answers
In LINUX(CentOS, RedHat) is there a way to have the banner statement appear before the logon instead of after the logon? In UNIX and Windows the banner appears before a person actually logs on, what I'm seeing in LINUX is that it appears after the login(ftp, telnet, SSH).

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
