Easy way to lock file with a password?

theKbStockpiler · 01-05-2014, 01:50 PM

Is there a method to lock a file from a general user but give them a password to open one directory or file without giving them the root password?

Thanks in advance!

You can do it with encryption. Encrypt the file(s) or file tree you want to protect and only give the password to authorized users. You can have different sets of files encrypted with different passwords.

I have a bunch of Rpm type Distros I'm using that are all non-updatable. Is there a command I could download and install to do this?

I use the ccrypt command to do what you want to do.

There is gpg, openssl and ccrypt as jailbait said.

I use ccrypt myself on a text file with my passwords and logins. Another command that is part of the ccrypt package is ccat. I use this command to quickly view the encrypted text file without re-encrypting it again. But, you still need the key to view it.
