Renewing ADFS Token Signing Certificate

Token signing certificates are standard X509 certificates that is used to securely sign all tokens that the federation server issues. Token decryption certificates are standard X509 certificates that is used to decrypt any incoming tokens. They are also published in federation metadata. Single Sign on breaks if it expires. In my case its used for several single sign on Apps like Zscaler / Cisco Jabber. Lets see how to Extend them to 1 year to 3 years and renew the same and update in zscaler.
