-- Use cryptsetup instead of zuluplay to unlock TrueCrypt volumes if installed
version of cryptsetup >= 1.6.0(released on January 14,2013).
-- Use cryptsetup instead of zuluplay to unlock VeraCrypt volumes if installed
version of cryptsetup >= 1.6.7(released on March 23, 2015).
-- The two changes above will hopefully solve long standing problems around
unlocking TrueCrypt/VeraCrypt volumes that use preboot authentication.
-- Use cryptsetup by default instead of dislocker to unlock BitLocker volumes
if installed version of cryptsetup >= 2.3.0(released on February 3,2020).
Users of cryptsetup >= 2.3.0 who prefer to use dislocker to unlock
BitLocker volumes should create a text file at "/etc/zuluCrypt/dislocker".
