The Linux Unified Key Setup (LUKS) is a disk encryption specification created by Clemens Fruhwirth in 2004 and originally intended for Linux.

What does LUKS do in Linux?
A common usage of LUKS is to provide full disk encryption, which involves encrypting the root partition of an operating system installation, which protects the operating system files from being tampered with or read by unauthorized parties.
How hard is LUKS to crack?
LUKS uses dm-crypt and 512-bit AES. Unless the person who set it up used something like “password” or “1234567” as his passphrase, you aren't going to decrypt it in anything like your remaining lifetime. You don't. Not only is it technically impossible, but also because that data doesn't belong to you.
Can LUKS be decrypted?
Decrypting LUKS2 devices in-place
Decryption can be done in either offline or online mode, using the cryptsetup command. Since cryptsetup version 2.5. 0 (2022) LUKS2 supports decryption by migrating LUKS2 header in a separate file.
How secure is Linux LUKS?
Linux, known for its robust security features, offers powerful tools for filesystem encryption: LUKS (Linux Unified Key Setup) and eCryptfs. These tools provide layers of security for data at rest, ensuring that confidential information remains confidential, even if it falls into the wrong hands.
