Hi Jiten,

I checked in the sros2 git repository upstream. It seems as if the reference to _x509 is present upstream as well.

I suggest filing an issue with the sros2 project to see if it is a problem. If you do, please reference the issue here.

Based on a Google search for the error message, it seems that this private member was removed in Cryptography 39.0.0. I think sros2 may need to be patched to use the correct API.

Regards,
Rob
