veracrypt-cli and veracrypt-gtk have been added to the prebuilt repo. Both have been tested on dCore-wheezy and dCore-artful in creating and mounting a file container so should work across all x86 dCore ports. They are conflicting packages, choose one or the other, veracrypt-cli is smaller and cli mode only. veracrypt-gtk can be used both as command line or graphical with X running.
Those using the most recent release candidate will have raid-dm-KERNEL imported with the right package for the current running kernel. Others need to import raid-dm-KERNEL with KERNEL being their current running kernel.
Veracrypt is the successor to Truecrypt which is now unmaintained, but Truecrypt will remain in the repo.
