function Import-PWSHYBKPIVKey { <# .SYNOPSIS Imports a private key into a PIV slot of a locally attached YubiKey. .DESCRIPTION Wraps "yubico-piv-tool.exe --action import-key". Overwrites any key already present in the target slot with no way to recover it, so this cmdlet supports -WhatIf/-Confirm with ConfirmImpact 'High'. Throws on failure rather than returning a value, matching Import- verb convention. Accepts the "import-key" action's config-declared options (-Slot, -Input, -KeyFormat, -Password, -ManagementKey, -PinPolicy, -TouchPolicy, -Reader) as dynamic parameters built from Config\Posh-YBKPIV.json. .PARAMETER Slot The PIV slot to import the key into, e.g. '9a'. .PARAMETER Input Path to the key file to import. .PARAMETER KeyFormat File format of the key: PEM, PKCS12, GZIP, DER, or SSH. Defaults to PEM when omitted. .PARAMETER Password Password protecting the input file (e.g. a PKCS#12 bundle), as a SecureString. .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 PinPolicy PIN policy to apply to the imported key: never, once, always, matchonce, or matchalways. .PARAMETER TouchPolicy Touch policy to apply to the imported key: never, always, or cached. .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 -Slot, -Input, -KeyFormat, -Password, -ManagementKey, -PinPolicy, -TouchPolicy, 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 Import-PWSHYBKPIVKey -Syntax` for the authoritative, current parameter list. .EXAMPLE Import-PWSHYBKPIVKey -Slot '9a' -Input 'C:\keys\key.pem' Imports the key from key.pem into slot 9a after confirmation. .LINK https://developers.yubico.com/yubico-piv-tool/Actions/ .LINK New-PWSHYBKPIVKey .LINK Remove-PWSHYBKPIVKey #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = 'High')] param() DynamicParam { $dynamicConfig = Read-PWSHYBKPIVConfigFile Get-PWSHYBKPIVActionParameter -Action 'import-key' -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'.
