I run an application on a linux server, and when I run the application I supply the password as a command line, like this:
./myapplication --smtp-password mypassword
In our application, we didn't built so far encrypt/decrypt , because it is supposed to be a very simple monitoring application, and it is very simple "pinging" and health check and send email in case of failure.
Any admin - and we have three other admins - can just list the process with ps, and see the command arguments, and figure out the password.
Is there a way to hide that?
