Spiegazione dello script

Lo script può essere usato direttamente senza alcuna modifica. All'amministratore viene chiesto la data di scadenza e se desidera visualizzare segreti o certificati già scaduti o meno.

Il comando "Add-Member" è responsabile della creazione delle colonne nel file CSV. È possibile modificare la variabile "$Path" direttamente in PowerShell, con un percorso di file CSV, nel caso in cui si preferisca che l'esportazione sia non interattiva.

Comando	Note
Get-MgServicePrincipal	Recupera un'applicazione aziendale dalla directory.
get-MgServicePrincipalOwner	Recupera i proprietari di un'applicazione aziendale dalla directory.
