How to encrypt a partition with DM-Crypt LUKS on Linux
TrueCrypt is no more, and the purpose of this post is to show you straightforward partition encryption with dm-crypt luks. DM-Crypt is transparent drive encryption that is kernel module and part of the device mapper framework for mapping physical block device onto higher-level virtual block devices, it uses cryptographic routines from the kernel’s crypto api. Long story short, device mapping encryption provided by the kernel “linux” crypto api.
