SPSTrust is a PowerShell script tool to configure trust relationships between SharePoint Server farms — exchanging STS/ROOT certificates, publishing service applications, granting Topology and published service-application permissions, and connecting service application proxies across farms.
It follows the Microsoft guidance Share service applications across farms in SharePoint Server and is compatible with SharePoint Server Subscription Edition.
