Cross-platform on-the-fly encryption. VeraCrypt provides cross-platform
on-the-fly encryption for Linux, MacOS X and Windows. It can encrypt
filesystems stored either within a file or on disk partitions. Supported
encryption algorithms include AES, Serpent and Twofish. The current
version uses the XTS mode of disk encryption. In addition, VeraCrypt
supports "hidden volumes" - unidentifiable volumes present in the
free-space of a VeraCrypt volume.

VeraCrypt is a fork of the old TrueCrypt. I know there are official DEB
files for VeraCrypt provided on their Web site (link below), but it's
not a repository, and the only repositories I can find are unofficial
OBS ones (such as
https://download.opensuse.org/repositories/home:/unit193:/veracrypt). I
think this would technically be in contrib, since it uses non-free
code/licensing. Nonetheless, I think this would be a good addition to
the Debian repositories, as there aren't that many other viable
file/partition encryption alternatives. Thank you.

As discussed in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=814352, it has
a shady licensing model making it DFSG incompatible. IDK why wnpp-check wouldn't
show that one, so I'll leave this message here.

Veracrypt already dropped TrueCrypt support, also it uses Apache License
so there's no more "shady licensing model making it DFSG incompatible",
could we reopen the issue for inclusion request? As you can see many
people already requested RFP for this package for many years.
