In My ubuntu, there are some confidential certificates in one directory. my colleagues know my root password and user password. Now i want to restrict to access that folder with password / security other than root password. I don't want to use any GUI based 3rd party applications. I want to DO it only through commands.
and one more is i tried ecryptfs. It is working fine. But i'm unable to access the files in protected directory through my C application. Help me how to access ecryptfs protected directory from c application.
Please suggest me some standard way to restrict.
