'_RSAPrivateKey' object has no attribute 'sign'

• [x ] I have checked that the SDK documentation doesn't solve my issue.
• [x ] I have checked that the API documentation doesn't solve my issue.
• [ x] I have searched the Box Developer Forums and my issue isn't already reported (or if it has been reported, I have attached a link to it, for reference).
• [ x] I have searched Issues in this repo and my issue isn't already reported.

Description of the Issue

When trying to access the folder structure from a Linux server, it sometimes succeeds, and sometimes I get:
File "/dist/shows/shared/lib/python2.7/site-packages/jwt/api_jws.py" in encode
114. signature = alg_obj.sign(signing_input, key)

File "/dist/shows/shared/lib/python2.7/site-packages/jwt/algorithms.py" in sign
313. return key.sign(msg, padding.PKCS1v15(), self.hash_alg())

Exception Type: AttributeError at /attachments/add/red/international/internationalizr/712768/
Exception Value: '_RSAPrivateKey' object has no attribute 'sign'

This seems to happen more often when the browser request to the server is coming from a Mac Big Sur. This doesn't make sense, since it is still the Linux server issuing the Box call.

Steps to Reproduce

rootFolder = self.client.folder(folder_id='0')
where self.client is the box client

Versions Used

Python SDK: 2.12.1
Python: 2.7.5

Hi @peternye

Which version of cryptography are you using? Can you run pip list and post the packages versions? You could try to upgrade cryptography as the problem could be related to that.

Thanks,

@peternye could you do the steps mentioned above?

[peternye]

Here are the versions we're using:

cryptography 1.7.2
jwcrypto 0.4.2
pycrypto 2.6.1

[mwwoda]

This issue could be related to the old cryptography version. Could you try to upgrade it to 3.x.x version? You can use the latests for python 2.7 which is 3.3.2.

[peternye]

I'm having problems getting this installed; waiting for help from Systems.

I upgraded to cryptography 3.3.2 and boxsdk 2.12.1. I'm now getting:
auth = JWTAuth.from_settings_file("/depts/tools/prodsoft/Sites/confs/box-config.json")
AttributeError: 'NoneType' object has no attribute 'from_settings_file'

[mwwoda]

This is probably the same issue as here #387. Refer to https://github.com/box/box-python-sdk#server-to-server-auth-with-jwt if you want to use JWT.

[peternye]

Worked!  pip install "boxsdk[jwt]" did it.
