That avoids the responsibility for a possible raise in Py_TYPE(args[...])->tp_name when the GIL is disabled.

Related to #16

This is good as is and it works as expected.

One idea for improvement: What about having a helper like:

/* Set a TypeError complaining that argument `argno` (named `argname`) must be
 * a string rather than the type of `obj`. Uses the %T format on Python
 * 3.13.0a6+, falling back to tp_name on older versions. */
static void
set_crypt_type_error(int argno, const char *argname, PyObject *obj)
{
#if PY_VERSION_HEX >= 0x030d00a6
    PyErr_Format(
        PyExc_TypeError, "crypt argument %d (%s) must be string, not %T",
        argno, argname, obj
    );
#else
    PyErr_Format(
        PyExc_TypeError, "crypt argument %d (%s) must be string, not %s",
        argno, argname, Py_TYPE(obj)->tp_name
    );
#endif
}

and then just calling it twice like:

set_crypt_type_error(1, "word", args[0]);

and

set_crypt_type_error(2, "salt", args[1]);

I have it implemented. Say yes and I'll push it here.

yes
