How to make script password protected?


I have written a script named scriptforhelp.sh where it has password added. Now I don't want any user to see the content.What tool/utility can I preferrably use?

Just set the owner of the file to you and remove reading permissions for other users:
chmod 700 file

or if other users are supposed to execute the file but should not read it:
chmod 711 file

Otherwise you can encrypt the file using gpg or similar.

In this regard this web site helps me:

http://www.linuxsecurity.com/content...117920/49/1/1/

I download the utility for linux from:

http://www.datsi.fi.upm.es/~frosal/

and install it commands are as follows:

tar -xzvf shc-X.X.tgz
cd shc-X.X/
make
make install


I use this command to encrypt

shc -f script.sh

it creates .x file

For ssh access, use public keys instead of username/password. For mounting an smb share, use the "cred=" option in "sudo mount ..." commands where the file is only readable by effective user running mount.

If it is a password that the user of the script has access to, have the enter it in manually instead of putting it in a world readable script. E.G. don't use "mysql -u $USERNAME $DATABASE -p$PASSWORD" but instead use "mysql -u $USERNAME $DATABASE -p".

Or if you want to hide other users from seeing this users password, have the password read from the users HOME directory where other users can't read it.

Use polkit to allow a local session regular user to perform the action. (If there is a polkit authorization to do it)

Configure sudo to allow the user to perform that command, while requiring the users password, so the target password can remain a secret.
