pkcs11_get_trust_store_slot

Selects an appropriate PKCS#11 slot to store trust assertions.

The slot to use is normally configured automatically by the system.

This will only return a valid result after the [func@pkcs11_initialize] method has been called.

When done with the Slot, use unref to release it.

Returns:

the Slot to use for trust assertions, or null if not initialized or no appropriate trust store could be found.
