OK, this is correct, but actually less infromation (only the salt) should do
also, and it does not answer the question how to create new hashes (i.e.: How
to prepare the "salt" parameter correctly for the various hash algorithms). The
manual page also does not mention any other algorithm than "classic DES" and
MD5 ($1$).
Real systems use newer algorithms however.
