Install Workflow Manager certificates in SharePoint Server
Secure Socket Layer (SSL) is an encrypted communication protocol which uses encryption certificates. Workflow Manager and SharePoint Server can communicate in a secure manor using SSL. This article describes the steps required to setup and configure SSL certificates.
The following sections provide instructions for configuring SSL communication with Workflow Manager and SharePoint Server.
Enable Secure Sockets Layer (SSL) in IIS Manager. For guidance on completing the configuration, see the following:
Install Workflow Manager certificates in SharePoint
Under some circumstances, you must obtain and install Workflow Manager "issuer" certificates on SharePoint Server. Here are the circumstances where you must install Workflow Manager certificates:
If SSL is enabled either on SharePoint Server (which is not the default) or on Workflow Manager (which is the default), AND
If SharePoint Server and Workflow Manager do not share a Certificate Authority, AND
If Workflow Manager is configured to generate self-signed certificates (which is the default).
Product trial, workflow development, and troubleshooting are easier if SSL is not enabled. However, communication between SharePoint Server and Workflow Manager is not encrypted if SSL is not enabled. For this reason, SSL should be enabled for production configurations.
To obtain and export certificates from the Workflow Manager server
On a computer that has Workflow Manager installed, choose IIS Manager, Sites. Right-click Workflow Management Site, and then choose Edit Bindings.
Choose the https port, and then choose Edit. Choose the View button in the SSL Certificate section.
To export the issuer certificate, do the following:
In the Certificate window, choose the Certification path tab.
Select root certification path and choose View.
On the Details tab, choose Export Certificate, and take the default options in the export wizard.
Give the exported certificate file a friendly name.
To install certificates on SharePoint Server
Copy the issuer certificate to your SharePoint Server computer.
Add the certificates to the Windows Certificate store.
For each certificate, do the following:
Double-click the file to open and view the certificate.
On the certificate, choose the Install Certificate button to start the installation wizard.
In the wizard, choose Place all certificates in the following store, and then choose Trusted Root Certification Authorities.
Add the certificates to SharePoint Server by going to the SharePoint Management shell and running the New-SPTrustedRootAuthority cmdlet. Do this for each certificate file.
