There seems to be no command-line tool that relies purely on the system
libcrypt (and implements exactly the set of algorithms supported by that)
to hash and verify passwords.

I have my Python nixcrypt library and accompanying example command-line
tool <https://gitlab.com/ldo/nixcrypt>, if you can be bothered to install
that.

I think you can also use the values in /etc/shadow on another system to
clone a user and password.

Yes, that will work, provided the hash algorithms used are compatible.
Which is usually the case, unless the system installations are from a few
years apart. Recommendations as to which hash algorithms to use (and which
to stay away from) tend to change somewhat over time.
