Qt for Python (PySide/Shiboken)

Hello again. I have successfully connected my qt app to a remote db by sqlalchemy and SSHTunnelForwarder. I was not able to use a proxy for this. The purpose is to create an app which will be distributed as a window application. In such case the Ssh credentials will be in clear, are you aware if, after compiling the files to get the exe, will be possible to find out the credentials?
