Script: Boost SIF Certificate Expiry Days

Cover Image for Script: Boost SIF Certificate Expiry Days

Overview

Millions of man hours have been lost due to Sitecore certs expiring on local dev machines after 2 years. Updating the cert can be time consuming, especially if you're running xConnect and have to update the cert in multiple places. Often times, it's easier to just reinstall Sitecore.

The script in this post will prevent that from happening in the first place by making a small change to the local installation of Sitecore Install Framework (SIF).

Script

Time to claw back some man hours. Run this script as an admin, either standalone, or include it as part of your custom installation scripts so that all of your devs benefit without having to lift a finger.

Inspiration for this script came from https://raghvendracodes.wordpress.com/2020/09/28/extending-sitecore-xconnect-client-certificate-expiration-date-during-sitecore-installation/

Stay BOOSTED,
