[OrchardCore 1.4.0] Windows server 2019, MachineKeys folder become huge easily

[PiemP]

I have an OrchardCore installation on Windows server 2019. My OrchardCore installation have enabled OpenId module and Workflow module to allow communications between OrchardCore and our custom application. I don't know what cause it but on the machine where is installed OrchardCore the folder C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys become really huge in a couple of month. A lot of certificate is owned by the user of the application pool related to the OrchardCore installation.

Is not a big problem but it's annoying.

I'm not sure, I suppose when use OpenId module to exchange data by graphQL to another application it generate certificate and store it in the MachineKeys folder.

I would like to better understand the problem to check if I do something wrong in my configurations.

Thank you.
