Did you mean -h?

It's not as simple as that, password  hashes are usually salted and
iterated. Salting means that the password is combined with a randomly
generated string stored in plaintext, which means that the password
doesn't hash to a fixed string.

I'm not sure exactly what you are trying to do, but crypt(3) may be of
help.
