I have a Lenovo pc and am running Ubuntu 20.04 LTS.

I would like to encrypt a file or directory on an external-HDD attached to the pc via USB port (to store data that should be VERY VERY SECURE).

How does one go about this?

How to Make an Encrypted File / Directory

Install p7zip-full from universe repository

Right click file or folder and select Compress.

Confirm archive name and select .7z, then Create.

Right click .7z archive select open with Archive Manager.

Select three line icon upper right, click Password to create AES-256 encrypted archive.

Notes

You will need to install 7Zip to open archive on a Windows machine.

Selecting and remembering a strong password is an important part of encryption security. There are many good articles about this topic on the internet.

HDD's, SSD's and flash drives can all brick without notice. SLC, (Single Level Cell) SSD's and flash drives have the longest life spans. It is a good idea to keep a backup drive and copy of the password in your safety deposit box.
