Plaxis - Python 'plxscripting'-'encryption'

Hello, I have a question to connect plaxis from a code in python.

Initially I got this error:
"ModuleNotFoundError: No module named 'plxscripting' "

And I managed to fix it by placing the following code:

" File "C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1 Update 1\python\Lib\site-packages\plxscripting\easy.py", line 26, in <module>
from .server import new_server as n_serv
File "C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1 Update 1\python\Lib\site-packages\plxscripting\server.py", line 39, in <module>
from .connection import HTTPConnection
File "C:\ProgramData\Bentley\Geotechnical\PLAXIS Python Distribution V1 Update 1\python\Lib\site-packages\plxscripting\connection.py", line 32, in <module>
import encryption
ModuleNotFoundError: No module named 'encryption' "

You know some lines with which I can get the 'encryption' module
