I have a script, written in C, which requires 3 parameters: host, name, password, like this:
./myscript 1.1.1.1 name mypassword
I call this using PHP exec command (need to, functionality not found in PHP).
exec('./myscript $host $name $password');
In linux, using ps command, I can see:
./myscript 1.1.1.1 name password.
How can I hide my password, that you can't see it on linux using ps?
Thank you.
There are example out there which does something you like: http://www.lenzg.net/archives/256-Basic-MySQL-Security-Providing-passwords-on-the-command-line.html Remember, your password is still visible for a fraction of time.
You could simply prompt the password after starting the executing of the C-script and forward the password via an pipe in PHP exec.
Since you are in a running environment. I'd temporary store your password in an environment variable (SET) and use this variable in your exec(). This way your password won't show up in ps.
