(1) The SSH Communications code bears their copyright. For me to use
it without permission (which was not granted) would be a copyright
violation;
(2) We would have implemented SSH ourselves from scratch except that
(i) the SSH public key authentication is flawed and opens the
host machine to several easy attacks when the client is
coming from a machine that has the home directories NFS
mounted; or if the client is Windows or MacOS.
(ii) SSH requires the use of RSA which is a patented algorithm
in the United States. The cost of a license is a minimum
of $100,000 and would require us to pay royalties on every
download of C-Kermit source and Kermit 95 patch file.
As a not for profit we cannot afford this.
(3) The SSH code is not designed to be used as a module for another
product. Whenever an error occurs it calls exit() which would
terminate K95.
However, to answer the question directly. It took me 14 hours to
take Gordon's port and turn it into a DLL that follows the K95
Network DLL API.
