Use TrueCrypt and VeraCrypt containers in Linux, natively

Here's something handy. A tutorial on how to use TrueCrypt and VeraCrypt containers natively in Linux without relying on either program by utilizing built-in kernel dmcrypt functionality, including flexibility of use on multiple platforms and processor architectures, legacy format, data ownership and mount point permissions, optional use of tcplay, some other tips and tricks, and more. I believe you will find this rather useful.
