I created a device with self-signed certificate using dps.

with common name device-id

Now, I want to add module to device. here want to generate new certificate with subject device-id/module-name

Can someone please help me with the steps for generating certificates for both device and module identity.

Should i use same key for both certificates?

I'm getting when i'm trying to connect to module using this connection string

`HostName=${hostName};DeviceId=${deviceId};ModuleId=${moduleId};x509=true;`

I'm getting unauthorized.

    Hello @Naga Lokesh Kanumoori ,

    welcome to this moderated Azure community forum.

    The Azure Device Provisioning service is not well equipped for working with module identities.

    Please check this blog post on how to work around this, the same way as Microsoft is doing this for their applications.
