Under linux / Ubuntu:
you have a .lastpass directory in your home folder.
There is a file that ends with _lpall.slps. This file contains 2 lines.
The second line is what we want (length: 24 ascii - base64 - characters). You need to base64 decode it. But you need the hexed version of this base64 string, in linux you simply do:
$ tail -1 *_lpall.slps | base64 -d | xxd -p
so you have a 32byte hex representation of the base64 string
Then you use this in you hash.txt file:
hex:iterations:email
