function Set-PWSHYBKPIVCcc { <# .SYNOPSIS Sets a new randomly generated CCC (Card Capability Container) on a locally attached YubiKey's PIV application. .DESCRIPTION Wraps "yubico-piv-tool.exe --action set-ccc". The CCC is part of how PIV-aware software recognizes and caches the card, so replacing it can affect existing enrollments; this cmdlet supports -WhatIf/-Confirm with ConfirmImpact 'High'. Throws on failure rather than returning a value, matching Set- verb convention. Accepts the "set-ccc" action's config-declared options (-ManagementKey, -Reader) as dynamic parameters built from Config\Posh-YBKPIV.json. .PARAMETER ManagementKey The management key authorizing the operation, as a SecureString. Defaults to yubico-piv-tool.exe's built-in default management key when omitted. .PARAMETER Reader Name of the smart card reader to target, when more than one is attached. If omitted, yubico-piv-tool.exe uses its own default reader selection. .INPUTS None. This cmdlet does not accept pipeline input. .OUTPUTS None. Throws a terminating error on failure; produces no output on success. .NOTES -ManagementKey and -Reader are declared dynamically from Config\Posh-YBKPIV.json and therefore do not appear in Get-Help's PARAMETERS/SYNTAX sections. Run `Get-Command Set-PWSHYBKPIVCcc -Syntax` for the authoritative, current parameter list. .EXAMPLE Set-PWSHYBKPIVCcc Sets a new random CCC after confirmation. .LINK https://developers.yubico.com/yubico-piv-tool/Actions/ .LINK Set-PWSHYBKPIVChuid #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'High')] param() DynamicParam { $dynamicConfig = Read-PWSHYBKPIVConfigFile Get-PWSHYBKPIVActionParameter -Action 'set-ccc' -CmdletWrapping $dynamicConfig.cmdletWrapping } begin { $config = Read-PWSHYBKPIVConfigFile Write-PWSHYBKPIVLog -Config $config -Level Debug -CmdletName $MyInvocation.MyCommand.Name ` -Message 'Cmdlet invoked' -BoundParameters $PSBoundParameters $architecture = Resolve-PWSHYBKPIVArchitecture -Architecture $config.installation.architecture $exePath = Get-PWSHYBKPIVInstallPath -Installation $config.installation -Architecture $architecture if (-not (Test-Path -Path $exePath -PathType Leaf)) { throw "yubico-piv-tool.exe was not found at '$exePath'.
