Creating a Self Signing Certificate

Creating a Self Signing Certificate using Akumina’s github powershell

Certificate Purpose:  In AppManger v5+, Akumina Streams, Site Manager and Forms Manager, uses the App Graph (AAD App), SharePoint “Application level permission 

  • Activity Streams – Tmonitor changes to subscribed SharePoint Lists and Libraries.  
  • Site Manager – To add sites to the AppManager.   
  • Forms Manager – To create SharePoint lists to store the form data.   

 To enumerate those changes in the SharePoint tenant, SharePoint needs a certificate as a secret via the “App Graph”. 

 To configure a Tenant to the Akumina Cloud, a certificate is required for the AppManager to make Graph App “Api” calls.  A purchased (length 2048) or self-signing certificate can be used.  The certificate will be uploaded as a thumbprint to the Graph App’s “Certificates & Secrets”.  A text version of the certificate and certificate password is required during the tenant configuration for the AppManager.  Below we will discuss creating a self-signing certificate.
