Is my terminal input secure?
My knowledge of Unix input/output/devices is very hazy so could someone please tell me if the following is secure?

I log on to an account on a shared Unix server (Linux 2.6.18-6-686) using ssh (PuTTY). I start a python program and then type into it (python raw_input command) the username/password of an account on a web site it should log on to using SSL. The python executable is one I downloaded and built myself. Is it possible for someone with root privilege to see the username/password I type into the python program?

Thanks very much in advance.
