Azure Databricks - AttributeError pgpy

Question

Dear Team,

I am using Azure Databricks to encrypt (.gpg) the file from data lake using pgpy library.

It was running fine for last few months and suddenly it's throwing below error message since yesterday.

Error Message:
AttributeError: module 'cryptography.utils' has no attribute 'register_interface'

Python Code:
import pgpy
from pgpy.constants import PubKeyAlgorithm, KeyFlags, HashAlgorithm, SymmetricKeyAlgorithm, CompressionAlgorithm
from timeit import default_timer as timer
import base64
import io

Looks like some issue with pgpy library. Could some one please check and suggest us what to do to ifx?

Thanks,
Divakar

Hello,
I have had the same error.

On September 7 the cryptography library was updated from version 37.0.4 to version 38.0.1, so the PGPy module is misaligned.

To fix this:

1. Remove the PGPy module via pip command
2. Install the cryptography module to the previous version "pip install cryptography == 37.0.4"
3. Install the PGPy module again.

This should temporarily fix the problem, until they update the PGPy library.

I hope I have been of help to you.

Best regards
