I need to encrypt a folder with documents (about 560kb if that makes any difference) and I was wondering whether it was possible to accomplish that using the command line?

I am searching for something like this:

encrypt /path/to/folder encryption_method password

than can be decrypted the same way

decrypt /path/to/folder encryption_method password
  • What counts as "unnecessary software"? The software to encrypt and decrypt would probably be necessary for this sort of problem, right? – Eric Renouf Nov 20 '16 at 12:31
  • I was referring to bloat-ware and it would be preferable to use the software that is pre-installed if there are any. Sorry if that was unclear. I will edit the question and remove that part completely. – Clone Nov 20 '16 at 12:36

    Have a look at encfsto have directories encrypted and used as filesystem to mount, even automatically with libpam-encfs. – ridgy Nov 20 '16 at 12:54

You are looking for dm-crypt and cryptsetup.

Basically you encrypt a block device and mount it as directory

You are looking for encfs: It mounts a dir on another dir, so that the files are stored encrypted as normal files. This way you do not need to make a block device.

Another nice option here is to use the tool that has been written by Dyne.

It is a nice set of scripts that handle a number of Unix tools to make encrypting Folders / Files easier.

Main page for the tool is here.
