What is LUKS and how does it work?

When sensitive information is available on any computer storage, certain measures have to be taken to keep it away from the prying eyes. And instead of just putting it behind an average password, one can convert this data into unreadable text, so that only an authorized person could decipher it and read the original content. This method of protection is widely known as encryption. On Linux, it can be implemented through LUKS, the kernel’s standard solution serving to encrypt entire disks. Let’s look closer at this technology and its working principles.
