Re: Credentials Caching - Security Guy Not Happy

I was thinking about this, even though, I have never looked at the
code, it seems to me that the server is much easier to secure than the
individual clients, so if the symmetric key were kept on the server and
was requested before each command that accessed the server, it could be
used to decrypt the authentication cache before executing the command.
This would make the command line client pretty secure so long as it
never cached the symmetric key locally. The server could generate real
the key out of a config file when it launched. I am not sure how
feasible this is just wanted to suggest it.
