Zulucrypt is a suite of applications for creating and managing volumes encrypted with luks, plain, truecrypt and veracrypt.
zulucrypt-cli is a command line interface frontend to cryptsetup and tcplay and it is a tool that make it easy to manage LUKS, PLAIN and TRUECRYPT encrypted volumes. With one command you can encrypt a volume. Without zulucrypt-cli would be multiple commands needed to achieve the same result.
