SPSTrust - SharePoint Trust Farm Tool

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 all supported on-premises versions (SharePoint Server 2016 to Subscription Edition).
