For the JtR-supported flavor of bigcrypt/crypt16, it should just work,
splitting the hashes into their halves on load.  There's another (even
weaker) flavor that JtR does not support (no demand).

What OS did the password file come from?  To my knowledge, bigcrypt-alikes
are used on at least some versions of HP-UX, SCO, OSF/1 (DU, Tru64),
Ultrix.

What version of JtR?

Can you please post one line from your password file that JtR doesn't
load?  (Obviously, change that password immediately.)

Thanks,
