We were able to renew the Symmetric Keys for the applications using the below PowerShell command
New-MsolServicePrincipalCredential -AppPrincipalId $AppID -Type Symmetric -Usage Sign -Value $newclientsecret -StartDate $dtStart -EndDate $dtEnd
Similarly, we want to renew Asymmetric keys for our apps whose keys are expired. How can this be done? Please suggest.
Request your assistance on the above.
