This can all be achieved by using the correct file permissions. If you don't want someone to read a file, don't give them permission to read it!

This may be done through the appropriate management of groups on your system.

Also - under Linux the zip and unzip programs allow oyu to specify passwords, and is compatible with pkzip Mike
