Well, I would either trace the syscalls that the "passwd" program is
making (when run by root as "passwd username") or reverse-engineer parts
of it (or, more likely, of a library that it uses).  Alternatively, the
same approaches may be applied to any daemon that does password
authentication or to the "login" program.  Running "strings" on some
program binaries or library files might be enough.

I haven't touched a SCO'ish system for many years, so I simply don't
know what changes they have made to password hash storage since then.
