function Remove-DbaDbAsymmetricKey { <# .SYNOPSIS Deletes specified asymmetric key .DESCRIPTION Deletes specified asymmetric 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 from which the asymmetric key will be deleted. .PARAMETER Name Name of the asymmetric key to be removed .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. .PARAMETER InputObject Allows passing in of AsymmetricKey objects from Get-DbaDbAsymmetricKey .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. .NOTES Tags: asymmetrickey Author: Stuart Moore (@napalmgram), stuart-moore.com Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Remove-DbaDbAsymmetricKey .EXAMPLE PS C:\> Remove-DbaDbAsymmetricKey -SqlInstance Server1 -Database Enctest -Name AsCert1 The Asymmetric Key AsCert1 will be removed from the Enctest database on Instance Server1 .EXAMPLE PS C:\> Get-DbaDbAsymmetricKey -SqlInstance Server1 -Database Enctest | Remove-DbaDbAsymmetricKey Will remove all the asymmetric keys found in the Enctrst databae on the Server1 instance #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "High")] param ( [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [string[]]$Name, [string[]]$Database = "master", [parameter(ValueFromPipeline)] [Microsoft.SqlServer.Management.Smo.AsymmetricKey[]]$InputObject, [switch]$EnableException ) process { if ($SqlInstance) { $InputObject += Get-DbaDbAsymmetricKey -SqlInstance $SqlInstance -SqlCredential $SqlCredential -Name $Name -Database $Database } foreach ($askey in $InputObject) { $db = $askey.Parent $server = $db.Parent if ($Pscmdlet.ShouldProcess($server.Name, "Dropping the Asymmetric key named $Name for database $db")) { try { #
