Cannot call hash_password with one argument

[Vayel]

The documentation gives this example:

@auth.hash_password
def hash_pw(password):
    return md5(password).hexdigest()

But this code raises two exceptions:

TypeError: hash_pw() takes 1 positional argument but 2 were given

After the above is fixed:

...
    return hashlib.sha512(password).hexdigest()
TypeError: Unicode-objects must be encoded before hashing

The following code works:

@auth.hash_password
def hash_pw(username, password):
    return hashlib.sha512(password.encode("utf8")).hexdigest()

I am using Python 3.7 and Flask is served through gevent.

Thanks!

Yes, I have updated the docs with the correct usage. Thanks!
