AttributeError: '_RSAPrivateKey' object has no attribute 'signer'

[nagappa2011]

I was just going through this implementation and it is really helpful..
I am getting this error when i try to generate pkcs7 request for certificate download. Since I need to use cryptography 38.0.3 for my other dependencies , Need to fix this issue in that version itself. Any Suggestions will be helpful .
Thanks in Advance..
Best Regards

Sorry i was not aware that a newer cryptography broke the package. I will have a look as soon as i can

Sure.. Thank a lot Mosen.. I think Signer and also signer_cert.public_key().verifier() both the places need changes... And One more thing what i observed is der_req = req.get_decrypted_envelope_data().. Not able to download CSR from der_req.. it complains about 6 extra bytes..

Apparently it was pulled from pyca/cryptography a little over a year ago after being depreciated for 4 years. pyca/cryptography#6639

yeah apologies i have not taken this project any further since the breakage. I can look at it but have very little spare time at the moment.
