I've been thinking about encryption in pppd. By reading my emails you've probably have an idea of what we do with pppd. Since I don't use
this. It is called ssh. Use it. Trying to overload ppp is not the way to do it ( and yes I know it is
done).
Note that tapping a modem comjunication is hard at the best of times due to cross training refections etc.
pppd to attach a windows desktop to a Linux server I was thinking about maybe an implementation of Blowfish type encryption between two pppd processes. There could be a command line argument that runs on encryption and the two processes could determine in the LCP phase that they are to encrypt all data between them. This is mainly for those individuals who think that the phone company will tap their line and see their data. Not very useful in tunnels since programs like vtun do the encryption for pppd.
Is this something that might be feasible? I'm not looking to add certificate based encryption like SSL but encryption like SSH, Vtun and others. Would a windows connection croak if it dialed into my box and my box wanted to use encryption? Would the windows ppp process be smart enough to reject that request? Has anything like this been tried yet?
Use ssh.
Thanks, Chris
