Among other things, Veracrypt is incredibly useful to have encrypted files or partitions readable by both Linux and Windows devices.
Some distributions have it packaged for aarch64, but none of them has it for armv7 or below, unlike the official download page: https://pkgs.org/search/?q=veracrypt, https://www.veracrypt.fr/en/Downloads.html
I was able to compile `veracrypt-git` AUR package on both armv7 and aarch64 devices. Also Debian Buster binaries that ship in the official download page can be run on ALARM.
