functions/Remove-DbaDbMasterKey.ps1
function Remove-DbaDbMasterKey { <# .SYNOPSIS Deletes specified database master key .DESCRIPTION Deletes specified database master key .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Database The database where the master key will be removed. .PARAMETER ExcludeDatabase List of databases to exclude from clearing all master keys .PARAMETER All Purge the master keys from all databases on an instance .PARAMETER InputObject Enables pipeline input from Get-DbaDatabase .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .NOTES Tags: Certificate, Masterkey Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Remove-DbaDbMasterKey .EXAMPLE PS C:\> Remove-DbaDbMasterKey -SqlInstance sql2017, sql2016 -Database pubs The master key in the pubs database on sql2017 and sql2016 will be removed if it exists. .EXAMPLE PS C:\> Remove-DbaDbMasterKey -SqlInstance sql2017 -Database db1 -Confirm:$false Suppresses all prompts to remove the master key in the 'db1' database and drops the key. .EXAMPLE PS C:\> Get-DbaDbMasterKey -SqlInstance sql2017 -Database db1 | Remove-DbaDbMasterKey -Confirm:$false Suppresses all prompts to remove the master key in the 'db1' database and drops the key. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess, ConfirmImpact = "High")] param ( [DbaInstanceParameter[]]$SqlInstance, [System.Management.Automation.PSCredential]$SqlCredential, [string[]]$Database, [string[]]$ExcludeDatabase, [switch]$All, [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.MasterKey[]]$InputObject, [switch]$EnableException ) process { if ($SqlInstance) { if (-not $Database -and -not $ExcludeDatabase -and -not $All) { Stop-Function -Message "You must specify Database, ExcludeDatabase or All when using SqlInstance" return } #
