Как вы защищаете пароль для папки в Linux / Unix без шифрования?

I have searched around quite a bit for either a built-in feature or program to do this, but had no luck. I want to password protect a folder, but do not want to encrypt it.

The security of the contents of the folder is not important, the password would just act as a deterrent to somebody attempting to access the contents of the folder from my computer. Think of it like a password lock on a computer, if you were to remove the hard-drive, you could easily take all the files the user had, but the password is still a deterrent to people accessing the contents of the drive.

Two main reasons for not using encryption here are:

• Decreased performance for opening files.
• Encryption prevents the contents from being indexed/searchable.

Is anybody aware of a solution?

The easiest way would be to change the permissions of the files so that they are not readable by anyone other than the owner. Once that is done, a user would have to either log in as you (which should require a password) or sudo as root (which should also require a password). To change the permissions, simply use the following command on any files you do not want others to have access to.

chmod og-rwx filename

This assumes that when you are not at your computer, your screen is locked and there is a password for your account as well as the root account.

Create a new user for these protected files and/or directories. Then replace $newuser with the new user account name:

• chown $newuser filename directoryname
• chmod og-rwx filename directoryname

This way, the files and directories are safe even if you do not log out and have your screen unlocked for some reason.
