A little knowledge is a dangerous thing.
a) Linux does NOT password hash with MD5. It uses a horribly convoluted hash
function which uses md5 amongst many other things to create the hash.
b)One cannot create collisions. One can generate two files which have the
same md5 hash. One cannot create a second file with the same md5 hash as
a given file.
c) If you want to use the hash for other purposes, the recommendation is to
use sha256.
