some problems of using Python's Cryptography on Windows

January 7, 2023

I would like to use the cryptography’s module on Windows, I am using version 1.12 and Python 3.10.6, and I have some problems. Actually, when I run my script, I receive the error :

    response = encode_base64(initial_response.encode('ascii'), eol='')
NameError: name 'encode_base64' is not defined

It is coming from the smtplib.py file. Also, I precise that the module works perfectly, I can use all the functions of the module base64. So the problem is coming from the word ‘encode_base64’. Please help !

I tried to launch my program, and that error occures, I expected that it was going to work.

>Solution :

You have a local module C:\Users/edoua/Documents\email.py that is shadowing the email module from the Python standard library. Rename email.py to something else, or move it to somewhere that isn’t on the Python path.
