use unix permissions.
say you have a script by userA that contains sensative data.
chmod 500. make is readable and executable by him and only him.
chmod 550, make it executable and readable for him and anyone in his group.
just remember that root can always read anyones data.
and if you have a file that has user/passwd entries in it you cna use perl to encrypt the file and decript it on the fly.

dh_installdeb
DH_INSTALLDEB(1) Debhelper DH_INSTALLDEB(1)
NAME
dh_installdeb - install files into the DEBIAN directory
SYNOPSIS
dh_installdeb [debhelperoptions]
DESCRIPTION
dh_installdeb is a debhelper program that is responsible for installing files into the DEBIAN directories in package build directories with
the correct permissions.
FILES
package.postinst
package.preinst
package.postrm
package.prerm
These maintainer scripts are installed into the DEBIAN directory.
Inside the scripts, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.
package.triggers
package.shlibs
These control files are installed into the DEBIAN directory.
package.conffiles
This control file will be installed into the DEBIAN directory.
In v3 compatibility mode and higher, all files in the etc/ directory in a package will automatically be flagged as conffiles by this
program, so there is no need to list them manually here.
package.maintscript
Lines in this file correspond to dpkg-maintscript-helper(1) commands and parameters. Any shell metacharacters will be escaped, so
arbitrary shell code cannot be inserted here. For example, a line such as "mv_conffile /etc/oldconffile /etc/newconffile" will insert
maintainer script snippets into all maintainer scripts sufficient to move that conffile.
A versioned Pre-Dependency on dpkg is needed to use dpkg-maintscript-helper(1). An appropriate Pre-Dependency is set in
${misc:Pre-Depends} ; you should make sure to put that token into an appropriate place in your debian/control file.

debhelper(7)
This program is a part of debhelper.
