The Linux Unified Key Setup, commonly abbreviated as LUKS, is an encryption standard designed for Linux-based operating systems. It provides a secure method to protect data on storage devices using full disk encryption. LUKS employs a user-supplied password or key to lock and unlock access to the data, adding an essential layer of security especially suitable for mobile devices or systems holding sensitive data.LUKS is widely supported and integrated within various distributions of Linux, making it a popular choice for users and administrators who require robust security measures. It is particularly noted for its compatibility with different encryption technologies, its ability to provide multiple user keys, and its strong cryptography practices.
