In the NSS upstream, it is difficult for this file to use
PORT_Assert, which is why this PORT_Assert was removed.

Do you want to keep this PORT_Assert in our copy of this file?

I think this is fine.

     memset(out_scalar, 0, 32);
 #ifdef IS_LITTLE_ENDIAN
     memcpy(out_scalar, MP_DIGITS(n), MP_USED(n) * sizeof(mp_digit));
