Help on import cryptography.x509 for splunk add-on

[spammenot66]

I'm using the Splunk Add-on Builder app to create a splunk app. on the run /test page of AoB, as soon as I add in the line from cryptography.x509 import certificate_transparency it throws the error below.As soon as I remove the line, base code from AoB immediate works but i need this cryptography to be avail

Traceback (most recent call last):

  File "C:\Splunk\etc\apps\TA-test\bin\pn_testtest_1598189382_409.py", line 14, in <module>

    import input_module_pn_testtest_1598189382_409 as input_module

  File "C:\Splunk\etc\apps\TA-test\bin\input_module_pn_testtest_1598189382_409.py", line 18, in <module>

    import cryptography.x509

  File "C:\Splunk\etc\apps\TA-test\bin\ta_test\cryptography\x509\__init__.py", line 7, in <module>

    from cryptography.x509 import certificate_transparency

ImportError: cannot import name certificate_transparency

I've added the paackages into the bin\ta_test folder:
cffi
asn1crypto
six
pycparser

[thambisetty · Accepted solution]

you should follow below while importing module into python:

for example 1:  you have certificate_transparancy.py is inside your_app\bin\ta_test

to import certificate_transparancy.py  in your python script which is in your_app\bin

from ta_test import certificate_transparancy 

for example 2:  you have certificate_transparancy.py is inside your_app\bin\ta_test\inside_folder

to import certificate_transparancy.py in your python script which is in your_app\bin

from ta_test.inside_folder import certificate_transparancy

@thambisetty Thanks for the reply. The problem was I tried to copy the site-package from Anaconda (C:\ProgramData\Anaconda2\Lib\site-packages), which was stupid. The solution was to install python,  then go to the scripts folder where python was installed to use pip.exe. 

I needed to just run pip install {module}, then copy the module along with all dependencies to the my splunk app as you've noted.
