You know on your machines that requires to be safe and secure. This might be customer information, business secrets, or your own individual details that you do not desire seen by the incorrect individual. To that end, you’ll go to some rather tough methods to secure that details.

However what if that job could be made substantially much easier? Some may not believe of the command line as the much easier choice, there are some CLI tools that do make brief shrift of a job.

Such holds true with7zip This tool is normally utilized for unzipping and zipping files, it likewise consists of the capability to encrypt and decrypt those files.

I desire to stroll you through the setup and use of 7zip for file encryption. I’ll be showing on Ubuntu Server, however the tool can be utilized on the majority of Linux circulations.

What you’ll need

How to install the 7zip bundle on Linux circulations

Possibilities are slim your Linux circulation consists of the 7zip bundle. In order to install the bundle that consists of the file encryption features, log in to your Linux machine, open a terminal window, and provide the following command:

sudo apt-get install p7zip-full -y

To install on a various kind of circulation, use a comparable command as revealed above, replacing apt-get for the similarity dnf or zypper.

That’s all there is to the setup.

How to encrypt files with 7zip

Let’s state you have the file webservers, which includes crucial details about the web servers in your information. To encrypt that submit with 7zip, concern the command:

7z a -p -mx= 9 -mhe -t7z webservers.7 z webservers

The choices utilized above are:

  • a: Add files to archive

  • – p: Trigger for a password

  • – mx= 9: Level of compression (9 being ultra)

  • – mhe: Encrypt file names

  • – t7z: Produce a 7z archive

You will be triggered to produce a passphrase for the file encryption. As soon as you have actually done that, the brand-new encrypted file webservers.7 z is developed.

You can likewise encrypt severalfiles State you have the files kubernetes and webservers to be secured into the file information.7 z. The command for this would be:

7z a -p -mx= 9 -mhe -t7z information.7 z webservers kubernetes

The above command would produce the encrypted information.7 z file, secured by the password of your option.

As soon as you have actually secured the files, you need to then erase the originals. Why? Due to the fact that those initial files (in our examples webservers and kubernetes) aren’t secured. Just the freshly developed.7 z files are secured. Erase those files with the command:

rm webservers kubernetes

How to decrypt files with 7zip

Those files would not be of any use to you if you could not decrypt them. How do you do that? We have the files information.7 z and webservers.7 z. With 7z, file decryption is done like so:

7za e information.7 z


7za e webservers.7 z

In either circumstances, you’ll be requested for the passphrase you developed throughout the file encryption procedure. If you stopped working to erase the initial files (which you should not disregard to do), 7z will ask if you desire to overwrite the existing files– in our examples that would be kubernetes and webservers (Figure A).

As soon as you have actually decrypted the file( s), you can then see their contents.

Which’s the essence of utilizing 7zip to encrypt and decryptfiles For anybody who requires strong command line file encryption on Linux, this may well be the perfect option for you.
