function Invoke-IBMrotateBitLockerKeys { <# .SYNOPSIS Rotates the BitLocker encryption key for Windows devices managed by Intune. .DESCRIPTION The `Invoke-IBMrotateBitLockerKeys` function triggers a rotation of the BitLocker encryption key on Windows devices managed by Intune. You can specify devices individually using `DeviceId`, `GroupName`, `DeviceName`, or `OS`. Additionally, you can choose to rotate the BitLocker key for all devices or select specific devices/groups interactively. .NOTES Author: Florian Salzmann | @FlorianSLZ | https://scloud.work Version: 1.3 Date: 2024-08-12 Changelog: - 2024-08-01: 1.0 Initial version - 2024-08-03: 1.1 Added filtering for only Windows Devices - 2024-08-06: 1.2 - Added batching / batch requests for large device collections and speed improvements (seperate function: Invoke-IBMGrapAPIBatching) - Aligment of all Action functions to the same structure - 2024-08-12: 1.3 - Optimized handling of unsupported OS #> param ( [parameter(Mandatory = $false, HelpMessage = "Specify the ID of the individual device to rotate the BitLocker key.")] [string]$DeviceId, [parameter(Mandatory = $false, HelpMessage = "Specify the name of the group that contains the devices for which to rotate the BitLocker key.")] [string]$GroupName, [parameter(Mandatory = $false, HelpMessage = "Specify the name of the individual device to rotate the BitLocker key.")] [string]$DeviceName, [parameter(Mandatory = $false, HelpMessage = "Specify the operating system of the devices to rotate the BitLocker key.
