pyOpenSSL layer for Python 3.12

[ismail-pitchstone]

Hi,

we were using Klayers-p38-pyOpenSSL:16 but it seems it is deleted. Klayers-p38-pyOpenSSL:18 does not work for 3.12 python on AWS Lamba. Getting the following error

ModuleNotFoundError: No module named '_cffi_backend'

ModuleNotFoundError: No module named '_cffi_backend'

Anyway to get Klayers-p38-pyOpenSSL:16 or is there any pyOpenSSL for Python 3.12 AWS Lambda

We don't support python3.8 anymore. Your best bet is to raise a pull request to build the package for python3.12. I'll be happy to merge it in once the PR is raised.

Hey
Thanks for the update. I would like to work on python 3.12 support. but no idea where to start. Probably updating python 3.8 build for python 3.12 will be the shortest path. Where can get 3.8 build?
Thanks

[keithrozario]

Don't need to build just raise a PR requesting PyOpenSSL for Python 3.12 and I'll merge it in

[ismail-pitchstone]

Ok. as I said I havent done anything like this before. Can you please guide me?
where can I get previously generated PyOpenSSL for Python 3.8? I can take it as a reference and try to update for python 3.12

[keithrozario]

Hey, it's actually quite simple.

Fork this repository. And you'll have a copy of it in your github profile.

You can then modify the config file for python3.12 to include pyOpenSSL. It's a csv, so please for the format.

Then commit that change to you fork.

And finally create a pull request to this repo to merge it in.

Once I merge it, the pipeline automatically builds the package.

Hope that helps.
